It accepts a 4 mm outside diameter tube and features a 1\/8 inch threaded port for installation into pneumatic equipment, manifolds, or valve bodies. Constructed from brass with a polybutylene tube insert, this connector handles working pressures up to 145 psi. It is a compact fitting at 26.10 mm overall length and weighs just 0.01 pounds, making it well suited for tight panel or cabinet installations. Licensed technicians and pneumatic system assemblers typically specify this fitting for instrument-grade air lines and light industrial pneumatic circuits.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in pneumatic tubing systems where a reliable, low-profile connection point is needed between flexible tubing and a threaded port. Common install scenarios include automation equipment, pneumatic control panels, air-actuated valves, and compressed air distribution networks in both light industrial and commercial environments. The push-to-connect design allows fast tube insertion and secure retention without ferrules or compression sleeves, reducing assembly time in high-volume or service applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free tube insertion and removal\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eAccepts 4 mm outside diameter polybutylene tubing\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch threaded port for direct installation into equipment\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect fitting for pneumatic tubing systems using 4 mm outside diameter tube and 1\/8 inch threaded ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by pneumatic system technicians or automation mechanics. Depressurize and lock out the compressed air supply before disconnecting or replacing any pneumatic fitting. Verify thread type and size match the receiving port before installation to avoid cross-threading or seal failure. Do not exceed the rated 145 psi working pressure in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/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: 26.10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Material\u003c\/strong\u003e: Polybutylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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\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: KCH04-01S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":51972181852466,"sku":"KCH04-01S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f95d2349f1037c4304ddd5a57945b175.jpg?v=1789963856","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kch04-01s-push-to-connect-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
