It terminates a compression fitting run without requiring a mating tube, blocking flow and pressure in the line. Rated to 2100 psi maximum working pressure, this plug handles a wide service temperature range from -65 degrees F to 250 degrees F (121 degrees C), making it suitable for demanding fluid and pneumatic system applications. At 0.02 pounds, it is a compact, single-piece fitting installed by HVAC technicians, plumbers, and fluid-systems mechanics as part of routine service or system modification work.\u003c\/p\u003e\n\u003cp\u003eThis plug is used wherever a compression tubing line needs to be capped or temporarily or permanently terminated. Typical applications include HVAC refrigerant line modifications, hydraulic and pneumatic control lines, instrumentation tubing, and general-purpose plumbing where compression fittings are specified. Its brass construction provides corrosion resistance suited to water, air, and a broad range of compatible fluids across both residential and light commercial installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression fitting end connection for tool-free tube insertion and reliable seal\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers corrosion resistance and durability in wet and dry service environments\u003c\/li\u003e\n  \u003cli\u003e2100 psi maximum working pressure rating supports high-demand pneumatic and hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eWide temperature range from -65 degrees F to 250 degrees F accommodates diverse service conditions\u003c\/li\u003e\n  \u003cli\u003eCompact, single-unit design sold individually for precise inventory control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube plug for use with standard compression-style tubing systems in HVAC, plumbing, pneumatic, and instrumentation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician, plumber, or qualified mechanical contractor. Depressurize and isolate the tubing line completely before removing any existing fitting or installing this plug. Hand-tighten the compression nut onto the plug body, then apply a controlled additional turn with an appropriate wrench to seat the ferrule without over-compressing it. Verify there are no leaks under operating pressure before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -65 degrees F (54 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 59HD-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538846056754,"sku":"59HD-4","price":17.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c8c9d107bf030c6dd0b99ac8b2dc122.jpg?v=1785828225","url":"https:\/\/voomisupply.com\/products\/parker-59hd-4-compression-tube-plug-brass-2100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
