O-Ring Hose Fitting

The VINTAGE AIR O-Ring Hose Fitting (Part No. 35841-VUG) is a 135-degree AC refrigerant hose end designed for custom cooling system installations in automotive climate control upgrades. This aluminum and steel construction fitting connects 6 AN hose with crimp termination to a 6 AN female O-ring port, providing a leak-free seal critical for high-pressure refrigerant applications in modern vehicle AC retrofits and restorations.

The 135-degree bend angle accommodates tight engine bay routing where direct perpendicular connections are impractical, while the O-ring face seal technology eliminates the need for thread sealant tape, reducing installation complexity and contamination risk. The natural aluminum finish paired with zinc oxide-coated steel components balances weight savings with corrosion resistance—important for systems exposed to moisture and temperature cycling. The 6 AN sizing (standard in modern air conditioning system design) allows smooth refrigerant flow while maintaining compatibility with contemporary AC component standards and crimped hose assemblies commonly used in performance cooling installations.

This fitting serves custom climate control builds, vintage vehicle AC system conversions, and aftermarket cooling upgrades where factory routing or component configurations require angled connection points. Buyers restoring classic cars with modern AC systems, building dual-cooling setups for high-performance engines, or designing custom mobile command systems benefit from VINTAGE AIR's proven refrigerant fitting reliability. The O-ring design ensures repeatability across multiple service intervals without degradation, critical in sealed systems where refrigerant leakage directly impacts cooling performance and efficiency.
