I have 1 VL4N-F13 [female] of 2 , that will cut the male o ring in half if you do not wet\lube with water the male before inserting\locking , not worth sending it back I only use them to disconnect my exterior loop and drain.
-I treat them with respect , not like a headphone jack or a electrical plug, slowly align them softly push them together if they don't go in ,I try again. if you force it it will cut the o ring.
