Constructed from Kynar (PVDF) with a black finish, this fitting handles up to 250 psi working pressure and carries a vacuum rating of 28 inches Hg, making it suitable for both pressure and vacuum service. The FKM O-ring seat provides reliable sealing compatibility with a range of fluid media. Licensed plumbers, HVAC technicians, and fluid system technicians install this type of fitting in instrumentation, chemical handling, and pneumatic or liquid distribution lines.\u003c\/p\u003e\u003cp\u003eThis bulkhead union is suited for residential and light commercial applications where tubing must pass cleanly through an enclosure wall, panel, or bulkhead. The 5\/16 inch OD push-to-connect design allows fast, tool-free tube insertion and secure retention without ferrules or threaded sleeves. Its Kynar body offers strong resistance to aggressive chemicals and UV exposure, making it appropriate for chemical feed systems, pool and water treatment equipment, and similar fluid handling environments where corrosion resistance is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design accepts 5\/16 inch OD tubing — no tools required for tube insertion\u003c\/li\u003e\n\u003cli\u003eKynar (PVDF) body provides excellent chemical and UV resistance\u003c\/li\u003e\n\u003cli\u003eFKM O-ring sealing material compatible with a broad range of process fluids\u003c\/li\u003e\n\u003cli\u003eRated to 250 psi working pressure\u003c\/li\u003e\n\u003cli\u003eVacuum rated to 28 inches Hg for suction-side service\u003c\/li\u003e\n\u003cli\u003eBlack color finish for easy visual identification in multi-line systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect bulkhead fitting for systems using 5\/16 inch OD tubing in pneumatic, liquid, or chemical distribution applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of bulkhead union fittings typically falls to licensed plumbers or instrumentation technicians working on fluid or pneumatic systems. Before servicing any line, depressurize and isolate the system completely.
