Product Questions & Answers (2)

Question by: Neal H on May 26, 2025, 9:07 PM
Will this plug work with standard JIC fittings? Just wanna make sure before I order.
Answer by: Customer Support on May 28, 2025, 6:46 AM
Yes, this adapter features a 37-degree JIC flare, so it should be compatible with any standard JIC 37-degree flared fitting.
Question by: Harold A on Jun 22, 2025, 10:56 AM
what exactly does the 37 degree flare mean on this thing, and does that match up with standard JIC fittings on hydraulic lines?
Answer by: Customer Support on Jun 23, 2025, 11:48 AM
JIC fittings use a 37 degree flare seat as their standard connection angle, so yes, this plug is built to mate directly with that thread and seat geometry. The 3/8-24 male thread is the standard JIC size for that fitting family. When you thread this into a female JIC port, the flared seating surface is what creates the seal, not a separate O-ring or gasket. It is a straight plug, meaning there is no elbow or offset, just a direct cap for an open JIC port you need to close off.
