AC Hose Crimp Ferrule - #6 Standard and Reduced Barrier, Zinc Coated Steel

ACS Part Number: ACF-6R

This AC hose crimp ferrule is the outer sleeve that locks your #6 air conditioning hose to its fitting for a permanent, leak-free connection. Also known as a crimp sleeve, hose sleeve, or crimp shell, each ferrule is precision-formed zinc coated steel, sized specifically for # 6 or 5/16" A/C hose, and built for automotive air conditioning service and custom line fabrication.

Choose your barrier type

Same dash size — different hose outside diameter. Pick the variant that matches your hose so the crimp seats correctly and holds system pressure:

Standard Barrier — fits standard-wall #6 barrier hose.

Reduced Barrier — fits the smaller OD of reduced-barrier #6 hose.

Not sure which hose you're running? Measure the hose OD or check our hose guide →. Matching the ferrule to the hose is the difference between a clean crimp and a comeback.
