Constructed from polypropylene with a tan color finish, it accepts 1\/4 inch outside diameter tubing on both ends and is rated to 150 psi. The push-to-connect design allows tool-free tube insertion and secure locking without threaded fittings or solder. Plumbers, HVAC technicians, and industrial service techs use this fitting when a fast, reliable inline union connection is needed in low-to-moderate pressure lines.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial plumbing, chemical handling lines, and pneumatic control tubing where polypropylene construction offers adequate chemical resistance. It is commonly installed in water treatment systems, RO plumbing, and tubing manifold assemblies. The 1\/4 inch OD size is standard in many small-bore fluid and air distribution applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows fast, tool-free tube insertion and removal\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi for low-to-moderate pressure service\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction provides good chemical resistance for water and mild chemical lines\u003c\/li\u003e\n  \u003cli\u003eAccepts 1\/4 inch OD tubing on both ends for inline union connections\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight form factor at 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation union fitting for systems using 1\/4 inch outside diameter push-to-connect tubing in fluid handling or pneumatic applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut off the fluid or air supply and depressurize the line completely before installing or removing this fitting. Ensure tubing ends are cut cleanly and squarely with a tubing cutter for a proper seal. Insert tubing firmly until it seats fully in the collet.
