DOT-approved air brake fittings

Our selection of plastic and composite PTC fittings includes DOT transportation compression air brake fittings, including Parker’s Prestomatic line.

Plastic fittings

We provide plastic water and beverage fittings. Fast & Tite, LIQUIFit, and TrueSeal fittings are all FDA compliant and NSF/ANSI 51. LIQUIFit is also NSF/ANSI 61, while Fast & Tite and TrueSeal composed of gray acetal are NSF/ANSI 61.

Composite fittings

Parker Legris and Prestolok PLP composite fittings are used in a variety of pneumatically-driven manufacturing operations. They are available in NPT, BSPT, BSPP, and metric threads.

Metal fittings

Parker’s metal PTC offering includes Prestolok PLM and the 316 stainless steel PLS series fittings. Prestolok PLM and PLS fittings are FDA compliant. Available thread types include NPT, BSPT, BSPP, and metric. They are robust and resist aggressive chemicals and corrosion. For this reason, they are used in wide variety industries ranging from food processing to life sciences and chemical processing.

Prestolok PLP metal fittings are commonly used in industrial applications involving air, inert gas, and vacuum. Unlike the composite PLP fitting, they are not FDA compliant and are available in NPT threads only. They do offer excellent corrosion resistance and feature a stainless steel grab ring.
