Constructed from Kynar (PVDF), this fitting handles up to 250 psi working pressure and is rated for a vacuum of 28 inches Hg, making it suitable for both pressure and light vacuum applications. The black FKM o-ring provides compatibility with a range of aggressive media. Installation requires no tools for tube insertion — the push-to-connect mechanism secures the tube end on contact. Licensed plumbers, HVAC technicians, and industrial pipe fitters commonly install this type of fitting in chemical handling, water treatment, and process piping systems.\u003c\/p\u003e\n\u003cp\u003eThis union fitting is sized for 3\/8 inch OD tubing on both ends, providing an inline straight connection with equal-size tube ends. Its Kynar construction makes it well suited for corrosive fluid service, deionized water lines, and chemical transfer applications where metal fittings are not appropriate. The FKM o-ring sealing element extends compatibility to fuels, oils, and many aggressive solvents. This fitting is packaged and sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design — no tools required for tube insertion\u003c\/li\u003e\n  \u003cli\u003eKynar (PVDF) body for excellent chemical and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFKM o-ring sealing element for compatibility with aggressive media\u003c\/li\u003e\n  \u003cli\u003e250 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003e28 inches Hg vacuum rating for light vacuum service\u003c\/li\u003e\n  \u003cli\u003eBlack color for easy visual identification in mixed-material piping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8 inch OD tubing in push-to-connect tube-to-tube union applications.
