Alternative Fuel Service (AFS) Ball Valves

High pressures, high flows, and ANSI compliant

With working pressures to 6000 psig (413 bar) at 250°F (121°C) and flow coefficients from 4.0 to 13.8, Swagelok's AFS ball valves handle demanding applications like fueling stations and other public domain uses in the compressed natural gas and hydrogen fuel industries. Certifications include ANSI/NGV 3.1 service valve certification to 3600 psig (248 bar) and ANSI/NGV 4.6 Class B certification to 4500 psig (310 bar).

Small bore tubing and fittings

Unlike pipe, installs without heat or weld gases

Because small bore tubing (3/4"-2") systems use no heat or weld gases and are so simple and fast to install, they are well suited for installation in hazardous areas and confined spaces. Bending tubing reduces the number of connections in the system. And compared to a piping system of comparable strength, tubing systems are substantially lighter. This means that tube systems are easier to install and to support. We have a wide range of surface finishes, materials, diameters, and wall thickness to suit your individual needs.


Each Swagelok hose is assembled with your choice of Swagelok tube fitting end connections. Available in single, twin or vent styles, and suitable for light and heavy duty applications, our TC series hose offers low pressure conveyance while our 8R series hose is suitable for low- and high-pressure on-vehicle applications. For additional on-vehicle and dispensing infrastructure applications, our NG series natural gas hose assemblies which are certified for NGV3.1-2014 Class B (on-vehicle applications outside the engine compartment) and NGV4.2-2014 Class A and Class D (dispensing systems).

Filters–FW, F, and TF Series

Some with ECE R110 approval for AFS applications

TF Series filters features.png

Swagelok’s tee-type filters have a filter element that can be replaced without removing the body from the system. Select TF series filters are available with ECE R110-type approval for use in alternative fuel service.

Snoop® Liquid Leak Detection

Leak-test CNG vehicle fuel systems and more

Swagelok's Snoop and Real Cool Snoop liquid leak detectors detect gas leaks in hard-to-reach areas and meet the performance requirements of NFPA 52 Section 6-12.2 regarding leak testing a compressed natural gas vehicular fuel system. Real Cool Snoop's sustained bubble action works even on very small leaks and vertical surfaces, and at temperatures as low as –65°F and as high as 200°F. Swagelok Northern California supplies alternative fuel customers with Snoop liquid leak detectors, Goop thread lubricants; SWAK, PTFE Tape, and PTFE-Free pipe thread sealants.
