#10 135 Deg Female O-Ring Fitting

The #10 135 Degree Female O-Ring Fitting from Vintage Air is a critical fluid-transfer component engineered for custom automotive cooling and air conditioning systems. This fitting serves enthusiasts and professional mechanics building custom engine bays, vintage restorations, and high-performance cooling loops where reliable, leak-free connections are non-negotiable. Whether you're installing a modern air conditioning retrofit in a classic muscle car or upgrading your street rod's climate control system, this o-ring fitting ensures dependable performance under pressure and thermal cycling.

Constructed with precision engineering, the 135-degree angle design allows for space-efficient routing in tight engine compartments where straight fittings won't fit. The female configuration accepts #10 male connection ports, making it compatible with standard -10 AN hose and tubing systems common in automotive climate control networks. The integrated o-ring sealing surface eliminates the need for external seals or Teflon tape, reducing assembly time and preventing contamination of your refrigerant or coolant circuit. This compact design—measuring just under 4 inches in length and weighing a quarter pound—integrates seamlessly into custom installations without adding bulk or compromising underhood aesthetics.

Mechanics and fabricators building custom air conditioning systems, turbo intercooler circuits, or prototype cooling solutions will appreciate the reliability and ease of installation this Vintage Air fitting provides. The 135-degree angle accommodates common manifold and condenser mounting positions while maintaining smooth fluid flow without sharp bends that cause pressure drops. Installation is straightforward—hand-tighten with a wrench to the appropriate specification to avoid over-torquing and damaging the o-ring seal. For best results, inspect the o-ring before assembly and ensure all mating surfaces are clean and free of debris.
