I tried to make the thread title as descriptive as possible.
First: I have a couple of Proteus industrial flow meters (reference my avatar) that have 9/16"-18 SAE thread. Previously I used the unusual and short-lived Danger Den (http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=203&products_id=2727) fittings when, I guess, Danger Den was experimenting with straight thread fittings as opposed to NPT tappered thread. Now, the watercooling world has switched to the BSPP G1/4" straight fitting, and I wonder if there is a way for me to use the G1/4" compression fittings on these flow meters. The thread diamter on the G1/4" fittings is slightly smaller than 9/16"-18 thread, but the difference is not large enough to enable the use of a reducer bushing (somewhere around 2mm difference in thread diameter). Perhaps an engineer or an automotive specialist can provide some input.
Second: I recently acquired second-hand compression fittings, and I thought it would be good to 'rejuvinate' the O-rings (they did not appear damaged, just used) by soaking them overnight in baby oil. Now it seems that it was not a good idea, as initially the rubber O-rings absorb the oil and thus expand, but eventually the oil will hasten the degradation of the O-rings. Are the soaked O-rings salvagable, or should they all be replaced?
Thanks for all input.
