It provides a secure, pressure-tight termination point for open tube ends in fluid or gas distribution systems. Rated to 3500 psi maximum working pressure and manufactured from ASME-SB75 and ASTM-B75 compliant brass, this plug is suited for systems where a reliable dead-end seal is required. With an overall length of 0.5 inches and a weight of 0.03 pounds, it is a compact, single-use termination fitting commonly installed by licensed plumbers, pipefitters, and HVAC technicians.\u003c\/p\u003e\n\u003cp\u003eThis compression tube plug is appropriate for residential and light commercial plumbing, pneumatic, and hydraulic tubing systems that use standard compression fittings. It terminates a tube run without requiring soldering or threading, making it suitable for retrofit work and service applications where a clean, removable seal is needed. It is a single-package quantity item with no minimum order beyond one unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction meets ASME-SB75 and ASTM-B75 standards\u003c\/li\u003e\n  \u003cli\u003eRated to 3500 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eCompression end connection — no solder or thread required\u003c\/li\u003e\n  \u003cli\u003eCompact 0.5 inch overall length for tight installation spaces\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.03 pounds — minimal added load on tubing systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube plug compatible with standard compression-style tubing fittings.

Depressurize and isolate the tubing system completely before installing or removing any compression fitting. Hand-tighten the plug onto the tube end, then apply the appropriate number of additional turns with a wrench per standard compression fitting practice — do not overtighten, as brass fittings can be damaged by excessive torque. Verify the system for leaks at operating pressure before returning to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 3500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME-SB75, ASTM-B75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwagelok Cross-Reference\u003c\/strong\u003e: B-400-P\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4 FNZ-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542390374706,"sku":"4 FNZ-B","price":20.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/561ac94125b17f74c4f5e5ab2a751951.jpg?v=1785899474","url":"https:\/\/voomisupply.com\/products\/parker-4-fnz-b-compression-tube-plug-brass-3500-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
