Constructed from Kynar (PVDF), this union 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 black color and FKM o-ring material indicate compatibility with a range of aggressive media where standard acetal fittings would be inappropriate. Licensed plumbers, HVAC technicians, and industrial pipe fitters install this fitting where a secure inline union connection is required without solvent cementing or threading.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for 1\/4 inch OD tubing runs in residential, commercial, and light industrial applications. Common install scenarios include chemical feed lines, condensate drain systems, instrument tubing, and process fluid lines where Kynar chemical resistance is specified. The push-to-connect design allows fast inline coupling and decoupling during system servicing. It is appropriate for use with compatible rigid or semi-rigid tubing meeting the 1\/4 inch OD specification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKynar (PVDF) body construction for broad chemical resistance\u003c\/li\u003e\n\u003cli\u003eFKM o-ring provides a secure, leak-resistant seal\u003c\/li\u003e\n\u003cli\u003e250 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003e28 inches Hg vacuum rating for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eTool-free push-to-connect operation for fast installation and removal\u003c\/li\u003e\n\u003cli\u003eBlack color coding for quick 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 union fitting for 1\/4 inch OD rigid or semi-rigid tubing in pressure and vacuum service lines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no tools for the push-to-connect engagement, but ensure tubing ends are cut cleanly and squarely with a tube cutter before insertion. Depressurize and de-energize the system fully before replacing or installing this fitting. Verify tubing OD tolerance and material compatibility with Kynar and FKM before use in chemical service. Follow applicable plumbing or mechanical codes for the installation jurisdiction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 (PVDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: FKM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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 inches Hg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 inches wide x 4 inches long x 2.25 inches high\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: FB4UC4-HBLK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540670185778,"sku":"FB4UC4-HBLK","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73590ca9d28fde7222dacb06af9678de_8454a2aa-504e-4f9e-9dcf-9342df92ee58.jpg?v=1785861445","url":"https:\/\/voomisupply.com\/products\/parker-fb4uc4-hblk-push-to-connect-union-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
