Thermochill Compression Fitting Preview

Thermochill Compression Fitting Preview
1/2” – 3/4” (19/13mm)

Intro

Over the past few months the liquid cooling industry has been turned upside down with the development and progression of the compression fitting. Were we’ve seen a major overhaul in the way we connect our hoses to our cooling components and the way we use fittings.

The compression fitting has evolved dramatically since the days of 10/8mm tubing. With so many different options available from major companies like Koolance and Bitspower. While Bitspower has been the main driving force behind the developments, offering a wide range of colour styles, endless angles and adapting pieces. Has it become a victim of its own success, with cheaper fittings appearing every other month?

However it seems there is still room for new comers, EK being one of them offering a cheaper alternative to the Bitspower Matt Black Range. And now Thermochill well established in the radiator market and new comers the coolant and fitting market. The description of the fitting on the WCUK website states.

“This new Compression fitting is the smallest ½” – ¾” Nickel Plated Compression fitting on the market which also offers the highest flow.”

But can this fitting live up to this statement.


I would like to thank Thermochill for sending me over some compressions fittings to play with.

Design

Thermochill have designed the fitting with functionally in mind; however looks haven’t been swept to the side. Designed for 1/2” ID – 3/4” OD hose (1/8” walls).

The compression fitting is made out of nickel plated brass and is built in two sections, the barb and the retention nut. The barb has a hexagonal base unlike most other conventional compressions which have circular griped base which allows the use of a spanner to tighten the fitting into a thread. The barb has a 9.5 mm flanged surface area for tubing 4mm of which is flanged.

The retention nut also features a hexagonal top which allows the user to tighten the nut with a spanner; the rest of the nut is grooved to allow the user to grip the nut for tightening.

Thermochill makes the fitting in both G1/4 and G3/8 inch threads, this allows for complete compatibility with components.

Comparison

With the bold statement provided with the Thermochill Compression fitting, It is important to find out how true the statement is.

“This new Compression fitting is the smallest ½” – ¾” Nickel Plated Compression fitting on the market which also offers the highest flow.”

With a range of fittings from some of the leading manufactures of Compression fittings, Bitspower, Feser and Primochill. The test is comparing overall width and and internal bore at both the thread and the barb of the fitting. Each of the fittings are measured with the same Electronic Digital Callipers as in the dimensions section above.

Cost

Price is a big aspect in the fitting market, with companies at each end of the scale. Thermochill have chosen to place themselves at the cheaper side. However don’t think of this as a bad thing, there are no issues with quality and no sign of machine marks on any of the fittings I received.

Priced at £3.56 a fitting on WCUK, the same price as a generic brand fitting but nearly half the price of a Bitspower Compression. And with the average price of a normal barb at £2 this seems to be one of the cheaper and best solutions to upgrading to compression fittings.

Interesting. Wonder what the U.S. cost will be and whether or not they will do other sizes.

Interesting.
I may be the only one, but there is one thing that I still don't fully comprehend on compression fittings.
How does the hose/tubing go in, and how are they held in place?
Any chance you could record a small video displaying it exactly?
I admit that the overall look of compression fittings are loads better than the norm. I still have reservations on how well they hold, even with more and more people using them.

durability? very thin wall compared to others.

I think it would be good if you can include a pair of these compression fittings with every PA series radiator you sell.

So many nice photos and not a single one with the collar off? Would have liked to see the flare on the barb itself.

Thanks bentleya. Also nice to have comparison measurements on the contenders.

@IFMU - boy, your questions made me feel good. I struggled for weeks before ordering compression fittings when they started to become the rage - because I had no idea how they actually worked. It's a lot easier to explain with a photo - and maybe bentleya will post one. But the simple explanation is, there are two parts - the barb and the collar. The main body screws into the water block/radiator/pump G1/4 opening. The "naked" fitting now looks like a regular barb - you can see it in the middle of the first comp fitting in bentleya's photo no. 1. The tubing goes over the barb just like normal. The collar (don't know the right term) slides over the tubing and then you screw it down to hold the tubing in place.

That's why it's important to get compression fittings with the proper ID and OD.

I had kinda figured it was something like that, just wasn't sure.
Thank you for explaining!!!
Maybe someday I'll be able to afford these things! lol

Thought that would make a big difference, good to know that as well.

Yeah, problem with compression fittings is that the tubing needs to fit very snuggly. Unlike normal barbs, which hold any OD as long as the ID is similar or smaller, if the ID and OD don't match the compression fitting, you wont get a waterproof seal, and you'll have leaking fittings.

Hopes for 3/8"ID. :D

Cheap with hex-nut. Brilliant.

bentleya

why didn't you separate the set? like remove the compression ring?

no 1:1 sized picture?

Very cool, thank you. ^_^

Nice Waterlogged. Now I remember that one - it helped me too!

Very happy to see that, if you can get to sell them at around 5$ in the us, they would be a huge seller. I dont like the look of the bp fitting but those look nice.

It's interesting (and sad) to me that they can't seem to ship near enough rads but they're working on other products. Can we get some pa rads in the states? How about some shrouds? Can they make a shroud for the 120.4? (or if they already have can you get it to resellers?)

Its functionality and affordability vs. aesthetics. The hexagonal base ruined the clean lines and sleek design of most compression fittings we all fell in love with.

They very solid and personally i can't see any problem with durability. As on a side note, the retention nut screwed down better on the Thermochill Fitting followed by the Bitspower. However the Primochill and TFC both jam up and are not smooth to screw down.

I'll said an email out to Thermochill in the morning, to see if, A) What other sizes will be made, B) When they will be come available to buy in the states and the rest of Europe.

WOW Thermochill, use one production facility for the rads and a different for the fittings. The rads are made in a small UK Factory and are turning out as many as they possibly Can.

The 140.3 has had a shroud for a long time. I think your'll be best to get in touch with Thermochill via the contact section on they website. As i'm sure they will answer it better than i did and can.

3/8id 5/8od and then they would have win.

The sooner that 1/2inch dies, the better we will all be. With all the testing Cathar did, I never understood why people didn't go down in size when he showed size didn't matter (almost no diff between 1/2" and 3/8").

idd, the difference is stupid, but letting 1/2" die, wouldn't be that good, 'cause the 1/2" barbs allow you to run 7/16 tubes without clamps, killer combo imho :)

More options can be better, I did use 1/2"ID but I have since switched to 3/8"ID, but its horses for courses some people like that size so it needs to be catered for.
Btw BentleyA, did TC mention about 3/8" to you at all?
Also if you have been using these for a while, how does the plating and finish stand up?

compressions are common nowadays. nearly every company seems to have some.

Rotary compressions are the ones these companies need to move into. Pretty much dominated by bitspower. Feser has some (though they leaked on my a few days ago; heard bitspower ones leak too though). A couple more have rotary but not with compressions. (enzotech, koolance)

They are very nice but the cost to move to 3/8 would be too much. New fittings for my 2 blocks, radiator and a new top for my D5 to convert it as well as all the tubing doent make it worth it.

I wonder if they are going to make some angled ones??

So where is the black version...:) I need more black options

It's a bit wierd. Seeing all worklogs i see more and more people prefering black. Yet only few vendors have such. Imho demand should drive offer?

Thanks, interesting preview

Compressions have been used in chill water HVAC applications for a long time now. As long as the tubing is in good repair, it will hold indefinitely. They work by squishing the tubing against the collar of the fitting, thereby creating a water tight seal. It's been my experience that compressions are more stable than clamps, but not as sturdy as worm screw type clamps. Most people prefer the look of compressions also.

At the moment Thermochill are working on some new Products and i have been told if they do release different size fittings it will be once all of the 1/2 x 3/4 have been sold.

Anyone know if these will fit on the EK HF Cu? It has been reported that the bitspower 1/2" comprossions don't fit but these are a little thinner.

I believe EK are changing the top slightly and should be ready around middle of May.
