Fitting Str 1/4 NPT to 3/8 Airline

The RideTech Fitting Str 1/4 NPT to 3/8 Airline adapter is a precision-engineered pneumatic connector designed for air suspension systems, pneumatic tool circuits, and compressed air applications requiring reliable thread-to-pushlock transitions. This straight adapter bridges the gap between 1/4 inch NPT (National Pipe Thread) male connections and 3/8 inch female pushlock airline fittings, making it essential for technicians, suspension specialists, and DIY builders working with modular air systems where compatibility between different fitting standards is critical.

Manufactured from brass and plastic composite construction, this straight fitting delivers durability while minimizing corrosion risk in moisture-prone environments common to pneumatic installations. The 1/4 inch NPT male thread provides a sealed, tapered connection that tightens as it threads into female ports, creating a leak-resistant joint without require thread sealant tape in many applications. The 3/8 inch female pushlock end accepts standard airline tubing with a simple push-to-connect mechanism, allowing for tool-free assembly and disassembly—a critical advantage when frequent maintenance or system reconfiguration is needed. The compact 1.15 x 1.15 x 3.1 inch profile and lightweight 0.04 lbs construction ensure minimal space consumption in crowded engine bays or tight suspension installations.

This adapter is ideal for custom air suspension builds, pneumatic control valve setups, and industrial pneumatic systems where mixing legacy NPT threaded components with modern pushlock tubing is necessary. Installation requires no special tools beyond standard wrenches for the NPT end; simply thread into the male port and push airline tubing firmly into the 3/8 inch female end until it seats. Technicians and hobbyists integrating RideTech or aftermarket air suspension kits often use these adapters to simplify plumbing between incompatible fitting types, reducing custom fabrication costs and assembly time while maintaining system reliability and pressure integrity.
