Description
Spring-lock & O-ring kit — Ford & Chrysler A/C
Everything to rebuild leaky Ford and Chrysler spring-lock A/C couplings in one box — 60 pieces of garter springs and HNBR O-rings in all four common sizes (#6, #8, #10, #12). Replace a tired spring and its O-rings to restore a positive, leak-free spring-lock connection.
What you’re getting
Fix the coupling, not the whole line
Rebuilds spring-locks
Fresh garter springs and O-rings restore the grip and seal of a worn Ford/Chrysler spring-lock coupling.
All four sizes
#6, #8, #10, and #12 covered, so you’ve got the right parts for the line you’re working on.
HNBR O-rings
Hydrogenated-nitrile O-rings resist refrigerant, PAG/POE oils, heat, and pressure.
Springs + seals together
Both wear items in one kit — a failing spring and a hardened O-ring usually go hand in hand.
Refillable
Each spring and O-ring is a stocked pack, so you can reorder just the size you use.
Shop-ready
Enough of each size to handle repeat repairs without reordering after every job.
