Quick Release Fitting wi th Viton Seal; Size: -4

The Quick Release Fitting with Viton Seal, Size -4 is a precision hydraulic and pneumatic connector engineered for high-performance fluid systems where rapid coupling and decoupling is essential. Designed for technicians, mechanics, and equipment operators who demand reliable, leak-free connections, this fitting serves critical applications in industrial machinery, aerospace systems, and tactical equipment. The -4 AN (Army-Navy) specification ensures compatibility with standard aerospace and military-grade fluid lines, making it indispensable for professionals who cannot tolerate connection failures.

This quick disconnect fitting features both male halves with aluminum construction and black anodized finish, providing excellent corrosion resistance and durability in harsh environments. The Viton seal—a fluorocarbon elastomer—ensures superior chemical compatibility and temperature stability across a wide range of fluid media, from synthetic hydraulic oils to coolants and solvents. The quick-release mechanism minimizes spillage and environmental contamination during disconnection, while the precision-engineered sealing surfaces prevent internal leakage that can compromise system performance and safety.

Best suited for integrators and maintenance professionals working with standardized AN hydraulic lines, this fitting excels in applications where frequent coupling changes are required without system downtime. The black anodized aluminum construction resists oxidation in both dry and humid conditions, extending service life in field environments. Installation is straightforward for anyone familiar with AN fittings; ensure all mating surfaces are clean and apply appropriate thread sealant to the male threads if the system design requires it. Verify compatibility with your specific fluid type—while Viton handles most common industrial and aviation fluids, system specification should always be confirmed before deployment.
