Push-to-connect couplers allow fast, tool-free hose connection and disconnection under pressure, reducing downtime on the job. This coupler is designed for compressed-air systems in shops, service bays, and industrial environments where reliable, repeatable connections are required. Licensed plumbers, HVAC technicians, and general maintenance trades working with pneumatic tool lines will find this coupler compatible with standard Industrial\/Milton Series fittings and plugs.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for general-purpose pneumatic applications including air tool lines, compressor outlets, and workshop distribution systems. The 3\/8-inch FNPT inlet threads directly onto standard male pipe fittings on compressors, manifolds, and drop lines. It is appropriate for both light commercial and industrial settings where the Industrial\/Milton interchange standard is the shop standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect mechanism allows fast hose attachment and release without tools\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch FNPT thread fits standard male pipe connections on compressors and distribution lines\u003c\/li\u003e\n  \u003cli\u003eIndustrial\/Milton Series interchange — compatible with the most widely used industrial coupler standard in North America\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight design at 0.365 pounds\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of one unit — available as a single replacement coupler\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or spare coupler for pneumatic systems using the Industrial\/Milton Series interchange standard with 3\/8-inch FNPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician. Depressurize the air line completely before removing or installing any coupler. Apply thread sealant tape to the male NPT fitting before threading on the coupler hand-tight, then wrench-tighten to a leak-free seal — do not overtighten. Verify there is no residual pressure in the line before connecting or disconnecting hoses.\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\u003eThread Size\u003c\/strong\u003e: 3\/8 inch FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Industrial\/Milton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.365 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: CN\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: HIGHLINE WARREN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 13-537\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-FLATE","offers":[{"title":"Default Title","offer_id":51721498001714,"sku":"13-537","price":23.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05e6235a0f787c44271d129f4a884326.jpg?v=1788578112","url":"https:\/\/voomisupply.com\/products\/highline-warren-13-537-push-to-connect-3-8-in-fnpt-coupler","provider":"Voomi Supply","version":"1.0","type":"link"}
