It accepts an 8 mm outside-diameter tube and connects to a 3\/8-inch threaded port. The body is brass with a polybutylene tube-contact sleeve, rated for a maximum working pressure of 145 psi. The overall installed length is approximately 34 mm. This fitting is suited for compressed-air distribution, fluid transfer, and light industrial pneumatic circuits. Installation does not require solder, ferrules, or compression tools, making it a time-saving choice for technicians building or servicing pneumatic panels and plumbing assemblies.\u003c\/p\u003e\u003cp\u003eThis connector is commonly used in pneumatic control systems, automated equipment, and compressed-air service lines where a reliable, low-profile straight connection is needed. It is appropriate for both bench assembly and in-place field repairs. The push-to-connect design is well established in HVAC controls, industrial automation, and light fluid-handling applications where 8 mm tubing and 3\/8-inch ported valves, manifolds, or cylinders are standard. A licensed technician or qualified pneumatic systems installer typically handles integration into pressurized circuits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTool-free push-to-connect design accepts 8 mm OD tubing\u003c\/li\u003e\n\u003cli\u003e3\/8-inch threaded port for direct connection to valves, manifolds, or fittings\u003c\/li\u003e\n\u003cli\u003eBrass body construction for durability and corrosion resistance in compressed-air service\u003c\/li\u003e\n\u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eRoHS compliant\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 34 mm for tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect replacement connector for pneumatic systems using 8 mm OD tubing and 3\/8-inch threaded ports in compressed-air and light fluid-transfer applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDepressurize and lock out the pneumatic circuit before removing or installing any fittings. Verify that the mating port thread form and size match before assembly. Insert tubing fully until it seats to ensure the internal collet grips correctly and the connection is leak-free. Pressure-test the completed assembly before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\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: 34 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Contact Material\u003c\/strong\u003e: Polybutylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance\u003c\/strong\u003e: RoHS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: KCH08-03S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":67908490854706,"sku":"KCH08-03S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1d244efe56773b6fa9b5f0cc3acd987.jpg?v=1791183728","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kch08-03s-push-to-connect-fitting-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
