It uses a Schrader Twist-Lock interchange, allowing fast, secure connections and disconnections under pressure. The body diameter measures 1\/4 inch with a 1\/4-18 NPTF thread, and it is rated for a maximum working pressure of 300 psi. Constructed from brass, this coupler resists corrosion and holds up to repeated use in demanding shop and field conditions. Licensed contractors, industrial maintenance technicians, and tool service professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for residential, commercial, and light industrial pneumatic systems where Schrader Twist-Lock fittings are the specified interchange standard. Typical applications include air compressor hose connections, pneumatic tool quick-connects, and service line fittings in HVAC, plumbing, and general mechanical shop environments. The 1\/4-18 NPTF thread ensures a pressure-tight mechanical seal without the need for additional thread sealant in many applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSchrader Twist-Lock interchange for fast, tool-free hose connection and release\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 NPTF thread provides a dry-seal, pressure-tight connection\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch body diameter fits standard Schrader-compatible couplers and plugs\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability in shop and field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or addition for pneumatic systems using Schrader Twist-Lock interchange fittings with a 1\/4-18 NPTF threaded port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanical or HVAC technicians.
