It delivers outlet pressure in the 200 to 3000 psig range and accepts inlet pressures up to 3000 psig, making it well suited for pressure vessel testing and dead-end testing applications. The body is machined brass with a brass housing cap, and the piston uses a Delrin cap bushing for smooth, repeatable pressure adjustment. A cartridge-type seat assembly with a PCTFE seat provides reliable shutoff and long service life. Two and a half inch brass gauges are included. Licensed gas technicians and industrial service professionals handle installation and commissioning of this regulator.\u003c\/p\u003e\u003cp\u003eThis regulator is intended for high-pressure methane and hydrogen gas systems where precise pressure control and robust construction are required. Its primary application is pressure vessel and dead-end testing, where delivery pressures must be maintained at elevated levels. The 350 CGA inlet connection accommodates standard high-pressure cylinder valves used in industrial gas service, and the quarter-inch Swagelok outlet connection with a quarter-inch stainless tube fitting suits instrumentation and test bench plumbing. It is sold as an individual unit and is appropriate for both fixed and portable test station configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMachined brass body and housing cap for durability in high-pressure service\u003c\/li\u003e\n\u003cli\u003eCartridge-type seat assembly with PCTFE seat for reliable sealing\u003c\/li\u003e\n\u003cli\u003eBrass piston actuation with Delrin cap bushing for smooth pressure adjustment\u003c\/li\u003e\n\u003cli\u003e350 CGA inlet connection with bronze sintered inlet filter\u003c\/li\u003e\n\u003cli\u003eQuarter-inch Swagelok outlet connection with stainless tube fitting\u003c\/li\u003e\n\u003cli\u003eExternal adjustable relief valve included on applicable range models\u003c\/li\u003e\n\u003cli\u003e2.5 inch brass gauges included for inlet and outlet pressure indication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with methane and hydrogen gas cylinders equipped with a 350 CGA valve outlet. Outlet plumbing requires a quarter-inch Swagelok-compatible stainless tube fitting.

Close the cylinder valve and bleed all downstream pressure before connecting or disconnecting the regulator. Inspect the CGA inlet connection and sintered filter for contamination before assembly. Never exceed the rated inlet pressure of 3000 psig, and verify all fittings are leak-free with an approved leak detection method before placing the system into service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Inlet Pressure\u003c\/strong\u003e: 3000 psig\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivery Pressure Range\u003c\/strong\u003e: 200 to 3000 psig\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 350 CGA with bronze sintered filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 0.25 inches Swagelok with stainless tube fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Machined brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuation Type\u003c\/strong\u003e: Brass piston with Delrin cap bushing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: PCTFE cartridge-type seat assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Size\u003c\/strong\u003e: 2.5 inches brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Compatibility\u003c\/strong\u003e: Methane, Hydrogen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 716352082570\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VICTOR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0781-1444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VICTOR","offers":[{"title":"Default Title","offer_id":51347235143986,"sku":"0781-1444","price":1628.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546341.jpg?v=1782099844","url":"https:\/\/voomisupply.com\/products\/victor-0781-1444-single-stage-high-pressure-piston-regulator","provider":"Voomi Supply","version":"1.0","type":"link"}
