Built from stainless steel and configured with an NPTF thread connection, this coupler is designed to maintain leak-free performance in demanding hydraulic systems. It accommodates a 4 mm (1\/4-inch) hose diameter with a 1\/4-18 thread size and carries a maximum working pressure of 6,700 psi. The overall length is 1.69 inches. With a maximum flow rate of 6.00 GPM, this fitting suits mid-flow hydraulic circuits where pressure integrity and corrosion resistance are priorities. It is installed by hydraulic system technicians and industrial maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for use in industrial hydraulic systems, mobile equipment, and high-pressure fluid lines where stainless steel construction is required for corrosion resistance or sanitary service conditions. The NPTF threaded connection provides a dry-seal fit, eliminating the need for additional sealant in properly matched port configurations. It is sold in a package quantity of two units, making it practical for paired connection points or having a backup on hand during service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaximum working pressure of 6,700 psi for high-pressure hydraulic service\u003c\/li\u003e\n\u003cli\u003eStainless steel construction for corrosion resistance in harsh or washdown environments\u003c\/li\u003e\n\u003cli\u003eNPTF dry-seal threaded connection reduces leak paths without additional sealant\u003c\/li\u003e\n\u003cli\u003e1\/4-18 thread size with 4 mm hose diameter compatibility\u003c\/li\u003e\n\u003cli\u003eMaximum flow rate of 6.00 GPM\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 1.69 inches for space-constrained installations\u003c\/li\u003e\n\u003cli\u003eSold in a package of 2 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the PARKER ST series.

Depressurize and bleed all hydraulic lines before disconnecting or installing any fittings. NPTF threads rely on thread-form interference for sealing — inspect threads for damage before installation and do not cross-thread. Verify system operating pressure does not exceed the 6,700 psi rating of this coupler.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6,700 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Diameter\u003c\/strong\u003e: 4 mm (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupler Size\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded (NPTF)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate\u003c\/strong\u003e: 6.00 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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-00078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544489099570,"sku":"PQ-00078","price":233.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5c62181709dcd64dcd1576b54f73026.jpg?v=1785927873","url":"https:\/\/voomisupply.com\/products\/parker-pq-00078-hydraulic-hose-coupler-6700-psi-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
