Machined from brass with a 1-1\/4 inch body diameter and a 1-1\/4 inch NPTF threaded connection, this Series 6100 coupler delivers a maximum working pressure of 2,750 psi. The wing nut design allows for hand-tightened, tool-free connection and disconnection under service conditions, making it practical for field use. It is rated for temperatures from -40 degrees F to 250 degrees F, giving it a broad service range across both cold-weather and high-heat environments. Hydraulic technicians and equipment mechanics are the primary installers.\u003c\/p\u003e\u003cp\u003eThis coupler is suited for mobile and stationary hydraulic systems in demanding work environments. Parker lists compatible applications as dump trailers, engine test stands, oil field equipment, and submersible pumps. The NPTF thread form creates a pressure-tight mechanical seal on assembly, which is a common requirement in these applications where leak-free connections are critical. The straight body geometry supports inline plumbing configurations without directional offset.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction for corrosion resistance in hydraulic fluid and oil service\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch NPTF threaded connection for pressure-tight, dryseal thread engagement\u003c\/li\u003e\n\u003cli\u003e2,750 psi maximum working pressure for demanding hydraulic circuits\u003c\/li\u003e\n\u003cli\u003eWing nut design enables hand-tightened field connections without additional tooling\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eStraight body shape supports direct inline plumbing configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with dump trailers, engine test stands, oil field equipment, and submersible pump hydraulic systems requiring a 1-1\/4 inch NPTF wing nut coupler rated to 2,750 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician. Before servicing any hydraulic connection, relieve all system pressure and verify the circuit is fully depressurized. NPTF threads require correct thread engagement to achieve the dryseal fit — do not cross-thread or overtighten. Inspect the mating port threads and sealing surfaces for damage before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2,750 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupler Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Wing Nut Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.84 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: 6125-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542473998642,"sku":"6125-20","price":444.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce0456d2c7572bd596537d83af67e449_6bd81eda-9caa-4cc6-8a0a-a40cf40373f5.jpg?v=1785901240","url":"https:\/\/voomisupply.com\/products\/parker-6125-20-hydraulic-wing-nut-coupler-1-1-4-in-2750-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
