It accepts 1\/4-inch outside diameter tubing and uses a 9\/16-18 UNF thread for secure panel mounting. The body is constructed from brass with a polybutylene collet, rated to a maximum working pressure of 145 psi. Installation requires no tools for tube insertion  -  the push-to-connect mechanism locks tubing in place on contact. This fitting is a standard component in pneumatic distribution systems and is typically installed by millwrights, pneumatic system technicians, and industrial maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for pneumatic plumbing applications where tubing must pass through a panel wall or machine enclosure and maintain a secure, leak-free connection on both sides. The bulkhead configuration allows a single fitting to bridge two zones while the push-to-connect ends on each side speed up assembly and servicing. It is appropriate for use in light industrial, automation, and OEM machine-building environments where compressed air lines are routed through cabinetry or structural panels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design on both ends  -  no tools required for tube insertion or removal\u003c\/li\u003e\n  \u003cli\u003eBulkhead-style body mounts through panels using the 9\/16-18 UNF thread\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eBrass body construction with polybutylene collet for durability and chemical compatibility\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range from 23 degrees F to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for pneumatic systems using 1\/4-inch OD tubing with a 9\/16-18 UNF bulkhead port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and lock out the pneumatic system before removing or installing any fittings. Thread the bulkhead nut onto the fitting body and torque by hand until snug, then secure with a wrench  -  do not overtighten brass threads. Ensure tubing is cut cleanly and squarely before insertion to achieve a positive seal in the push-to-connect collet. Confirm all connections are leak-free with a pressure test before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 29.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 23 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass body, Polybutylene collet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: RoHS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: SMC PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KQ2E07-00A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52043882103090,"sku":"KQ2E07-00A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82cb1559983eac9a5db5c3d13bc3ca69_34477942-8727-4806-afa7-023a91830c3f.jpg?v=1790029443","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2e07-00a-bulkhead-union-fitting-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
