#10 Straight O-Ring Beadlock Heater Fitting

The #10 Straight O-Ring Beadlock Heater Fitting from Vintage Air is a precision cooling system connector designed for hot rod, custom truck, and classic car builders who demand reliable fluid transfer in high-performance heating and air conditioning systems. This fitting serves as the critical link between heater core lines and custom climate control installations, making it essential for builders modernizing vintage vehicles with contemporary HVAC solutions. Whether you're installing an aftermarket heater core in a restomod or upgrading a street machine's cabin climate control, this straight configuration eliminates unnecessary angles that can restrict coolant flow or create stress points in aluminum tubing networks.

The #10 size designation refers to the SAE hose port standard, accommodating hoses with approximately 5/8-inch inner diameter—ideal for mid-range cooling capacity applications. The o-ring beadlock design creates a positive mechanical seal without requiring traditional hose clamps, allowing for quick-disconnect capability and eliminating corrosion points where clamps would normally sit on aluminum fittings. This straight configuration minimizes turbulence and pressure drop compared to 90-degree or 45-degree alternatives, maintaining consistent coolant velocity through the heater matrix and ensuring even cabin heat distribution. The compact 3.85 x 1.75 x 5.5 inch footprint makes it suitable for tight engine bays where space constraints limit fitting options, and the lightweight 0.25-pound construction adds negligible mass to your cooling system.

Builders installing Vintage Air climate control kits, custom heater setups, or performance cooling upgrades will find this fitting compatible with standard 5/8-inch SAE hose lines and beadlock-style quick-disconnect couplers common in modern automotive HVAC systems. The straight male port configuration works equally well in engine compartment-to-firewall runs or interior cabin heater core connections where direct line routing improves system efficiency. Installation requires no special tools beyond basic hose crimpers for beadlock fittings, and the aluminum construction resists corrosion when used with proper coolant inhibitors. Verify hose ID compatibility before ordering to ensure a proper beadlock seal and maximum performance from your custom climate control system.
