It uses a uniport design that combines the piercing and servicing functions into a single connection point, eliminating the need for separate access fittings. The valve seals with refrigerant-resistant O-rings and features a spring-loaded needle that automatically back-seats after servicing, leaving the refrigerant line free of restriction. Compatible with 1\/2 inch and 5\/8 inch OD tubing, it mounts with two socket-head screws. A hex wrench is included with each valve. Licensed HVAC technicians use this valve for quick line access during system diagnostics and refrigerant service.\u003c\/p\u003e\u003cp\u003eThe qtm-2 is suited for residential and light commercial HVAC refrigerant line applications where a permanent or temporary access point is needed without brazing or cutting the line. The integral needle depressor and wing cap allow the technician to pierce the line by hand, then connect any standard charging hose with a built-in depressor. Once the hose is removed, the spring-loaded needle reseats automatically, and the wing cap provides a secondary seal. This makes it a common tool for field service calls on air conditioning and heat pump systems where quick refrigerant access is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUniport design provides a single connection point for both piercing and servicing the refrigerant line\u003c\/li\u003e\n\u003cli\u003eSpring-loaded needle automatically back-seats after hose removal, leaving line unrestricted\u003c\/li\u003e\n\u003cli\u003eRefrigerant-resistant O-rings provide a leak-proof seal after servicing\u003c\/li\u003e\n\u003cli\u003eMounts to tubing using two socket-head screws; hex wrench included\u003c\/li\u003e\n\u003cli\u003eWing cap serves as a secondary precautionary seal after the needle depressor is discarded\u003c\/li\u003e\n\u003cli\u003eCompatible with standard charging hoses equipped with a built-in depressor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on refrigerant lines with 1\/2 inch and 5\/8 inch OD tubing in residential and light commercial HVAC systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with applicable EPA Section 608 regulations and local codes. Power down the system and relieve system pressure as appropriate before attaching the valve body to the tubing. Mount the valve using the provided hex wrench and socket-head screws, ensuring even clamping on the tubing. Discard the needle depressor after use and confirm the wing cap is fully seated to maintain the secondary seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD Size\u003c\/strong\u003e: 1\/2 inch and 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware\u003c\/strong\u003e: Two socket-head screws; hex wrench included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Refrigerant-resistant O-rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIVERSITECH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: qtm-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIVERSITECH","offers":[{"title":"Default Title","offer_id":51383595237682,"sku":"QTM-2","price":16.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674090.jpg?v=1782601599","url":"https:\/\/voomisupply.com\/products\/diversitech-qtm-2-line-piercing-valve-1-2-in-5-8-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
