Question by: Duane P on Sep 8, 2025, 9:54 PM
what's the E-Z CLIP SYSTEM about, and does this fitting work with it out of the box?
Answer by: Customer Support on Sep 10, 2025, 4:07 PM
That system is built to speed up hose assembly by replacing traditional crimping or swaging with a clip-based attachment method. This fitting ships as part of that system, so there's no extra adapter or conversion needed. The -12 dash size tells you the hose diameter it's matched to, and the female SAE 45-degree flare end handles the connection on the line side. Carbon steel construction keeps it solid across a broad range of working conditions.

Question by: Kirk R on Oct 30, 2025, 10:58 AM
trying to swap out a fitting on a -12 hose, is this one the right dash size?
Answer by: Customer Support on Nov 1, 2025, 10:03 AM
Hose dash size is the key match point here, and this fitting is made for a -12 hose. It is an E-Z CLIP SYSTEM nipple assembly with a female SAE 45 degree flare end.
