The body is constructed from Kynar, a chemically resistant thermoplastic well suited to aggressive fluid and gas environments. An FKM o-ring provides the primary seal, offering strong resistance to hydrocarbons, solvents, and high-temperature media. Rated to 250 psi and capable of handling a vacuum rating of 28 in-Hg, this cap is appropriate for a wide range of industrial and process-control plumbing applications. Technicians in HVAC, refrigeration, chemical process, and instrumentation work install this type of fitting where a tube end must be capped cleanly and securely.\u003c\/p\u003e\n\u003cp\u003eThis fitting cap is used to dead-end 1\/4 inch OD tubing in fluid handling systems, pneumatic circuits, and instrumentation lines where chemical compatibility and pressure integrity are required. The Kynar construction makes it particularly appropriate for applications involving corrosive chemicals, chlorinated water, or aggressive industrial fluids where brass or standard thermoplastic fittings would be unsuitable. Its black color allows for quick visual identification in systems where color coding is used to distinguish fluid types or pressure zones.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKynar body construction provides excellent resistance to corrosive chemicals and solvents\u003c\/li\u003e\n  \u003cli\u003eFKM o-ring seal rated for hydrocarbon and high-temperature fluid compatibility\u003c\/li\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free installation and removal\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi working pressure\u003c\/li\u003e\n  \u003cli\u003eVacuum rating of 28 in-Hg supports use in low-pressure and vacuum systems\u003c\/li\u003e\n  \u003cli\u003eBlack color for easy visual identification in multi-line installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect cap fitting for 1\/4 inch OD tubing in industrial fluid handling, pneumatic, and instrumentation systems requiring chemical-resistant materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by pushing the tubing firmly into the collet until it seats fully against the o-ring. Always depressurize and de-energize the system before removing or installing tube fittings. To release the fitting, press the collet ring inward while withdrawing the tube. Verify that tubing OD is within the fitting manufacturer's tolerance and that the tube end is cut clean and square before insertion to ensure a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Kynar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: FKM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Rating\u003c\/strong\u003e: 28 in-Hg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FB4CAP-HBLK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540982497586,"sku":"FB4CAP-HBLK","price":28.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e729417e41472fc428370c4be71ff08.jpg?v=1785866928","url":"https:\/\/voomisupply.com\/products\/parker-fb4cap-hblk-push-to-connect-cap-1-4-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
