It features a 3\/8-18 NPTF threaded connection and is designed for a 6 mm hose size with a coupler size of 0.375 inches. The overall length is 1.75 inches. This coupler is part of the Parker ST Series and is built for high-pressure hydraulic plumbing applications. Licensed hydraulic technicians and industrial plumbers install this fitting where a reliable, leak-resistant threaded connection is required in demanding fluid-power systems.\u003c\/p\u003e\u003cp\u003eThe PQ-00079 is suited for use in industrial and mobile hydraulic systems where high working pressure and corrosion resistance are priorities. The stainless steel construction makes it appropriate for environments exposed to moisture, chemicals, or washdown conditions. With a maximum flow rate of 12.00 GPM and a compact 1.75-inch overall length, it fits into tight plumbing configurations typical of hydraulic power units, cylinders, and valve assemblies in both stationary and mobile equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5,500 psi maximum working pressure for high-pressure hydraulic circuits\u003c\/li\u003e\n\u003cli\u003eStainless steel construction for corrosion resistance in harsh environments\u003c\/li\u003e\n\u003cli\u003e3\/8-18 NPTF threaded connection for a dryseal, leak-resistant fit\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate of 12.00 GPM supports demanding hydraulic flow requirements\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1.75 inches for installation in confined spaces\u003c\/li\u003e\n\u003cli\u003eParker ST Series design for consistent dimensional and performance standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for hydraulic systems using 6 mm hose with 3\/8-18 NPTF threaded ports operating up to 5,500 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid-power systems. Depressurize and fully isolate the hydraulic circuit before removing or installing any fitting. NPTF dryseal threads are designed to seal on thread engagement alone, but verify thread condition and apply appropriate thread sealant per system requirements. Torque to the fitting manufacturer and system specifications; do not overtighten stainless steel threads to avoid galling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupler Size\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5,500 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 12.00 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: PQ-00079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540570407218,"sku":"PQ-00079","price":250.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21dd58600e6c178d07d513768d9f8776.jpg?v=1785858715","url":"https:\/\/voomisupply.com\/products\/parker-pq-00079-hydraulic-hose-coupler-5500-psi-6mm-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
