Swagelok Tubing Pressure Rating, Material range: Swagelok and Hoke run more exotic alloy options (Monel, Hastelloy C-276, Alloy 400). A Swagelok cap serves as an external closure that threads onto tube fittings, while plugs insert directly into the tube or fitting bore. Where these end connections are not listed, a tube adapter can be used to create a two-piece ass embly. Tubing nominal length is 20 ft. For higher pressures, see the Swagelok Medium- and High-Pressure Fittings, Tubing, Valves, and Accessories catalog, MS-02-472. 3 and ASME B31. Except as noted, allowable pressure ratings are calculated from S values as specified by ASME B31. Rating based on repeated pressure testing of the Swagelok tube fitting with a 4:1 design factor based upon hydraulic fluid leakage. Swagelok® offers medium- and high-pressure fittings, tubing, valves, and related accessories with temperatures up 1000°F (537°C), pressure ratings up to 60 000 psig (4134 bar) in sizes ranging from 1/4 to to 1 in. Parker HNV up to 6,000 psi. For more information about pressure ratings of valves with tube fitting end connections, see Swagelok® Tubing Data, MS-01-107. A Swagelok tubing cap is a reliable, leak-proof seal for tube ends, essential in industrial and DIY fluid systems. End connections: All three offer compression, NPT, and tube-weld. Other cracking pressures are available; contact your authorized Swagelok sales and service representative. Reliable Swagelok Fluid System Components and Assemblies We apply expertise in product design, materials science, and manufacturing to supply a broad portfolio of high-quality fluid system products used in fluid system applications in diverse industries around the world. Both components provide leak-tight sealing under extreme pressures, yet each Pressure rating spread: Swagelok 1RS and 1VS series cover up to 10,000 psi. for medium-pressure products and 1/4 to 9/16 in. NACE® MR0175/ISO15156 compliance is available. The document provides detailed information on tubing, fittings, and valves, including their dimensions, pressure ratings, and ordering information for both metric and imperial sizes. Mar 27, 2026 ยท When selecting closure solutions for high-pressure applications, understanding the differences between Swagelok caps and plugs becomes critical for system safety and performance. It ensures secure connections, especially in high-pressure and corrosive environments, with 316 stainless steel offering superior durability and resistance. Ratings for the end connections used in this catalog are identified below. Pressure ratings for valves with Swagelok tube fitting ends may be lower due to the tubing pressure rating. The accompanying tables show working pressure ratings of tubing in a wide range of wall thicknesses. 1. 3, Process Piping. Calculations are based on maximum outside diameter and minimum wall thickness. Hoke 2200/2300 series stops at 6,000 psi. The accompanying tables show working pressure ratings of tubing in a wide range of wall thicknesses. Refer to Tubing Data catalog, MS-01-107, for additional information. 8 MPa) for ASTM A269 tubing at –20 to 100°F (–28 to 37°C), as listed in ASME B31. for high-pressure products. These include fittings, valves, pressure regulators, hoses, rigid and flexible tubing, tube accessories, gauges and other Medium and High Pressure Fittings FK and IPT, Tubing Valves and Accessories Swagelok® offers medium- and high-pressure fittings, tubing, valves, and related accessories with temperatures up 1000°F (537°C), pressure ratings up to 60 000 psig (4134 bar) in sizes ranging from 1/4 to to 1 in. Swagelok medium-pressure ends are rated to the working pressure of the tubing as listed below. . Allowable working pressures are calculated from an S value of 20 000 psi (138 MPa) for ASTM A269 tubing at –20 to 100°F (–28 to 37°C), as listed in ASME B31. NACE® MR0175/ISO15156 The options include high-purity and general industrial tube butt weld fittings, socket weld fittings, weld adapters, and subsea weld fittings. 3, except as noted. For more information on tube adapters, see the Swagelok Gaugeable Tube Fittings and Adapter Fittings catalog, MS-01-140. Compare Parker versus Swagelok compression fittings for pressure ratings, ferrule compatibility, sealing performance, and industrial reliability today. Not recommended for use with Swagelok tube fittings in gas service. Miniature Swagelok Micro-Fit ® fittings provide the same flow and service ratings as larger fittings in a compact design for tight spaces. Parker mostly stainless and brass. Allowable working pressures are calculated from an S value of 20 000 psi (137.
