PTFE Smooth-Bore, High Pressure Hose

PTFE smooth-bore, high pressure hose are the ideal choice for many chemical, gas, and high-purity applications. The broad Unisource line-up of PTFE hoses are ideal for each of these situations. Known as 3000 PSI, 5000 PSI and 6000 PSI hose specs (depending on size), these hoses are available in different reinforcing styles–braid, bunch braid, and spiral/braid combinations. Reinforcing is made of Series 300 stainless steel. PTFE is a fluoropolymer that provides the industry’s best all-around chemical resistance. At the same time, it offers both a very high (up to +450 Deg. F.) and low temperature rating (-65 Deg. F.). In addition, PTFE hose is virtually non-aging. It withstands continuous flexing, vibration and impulse. PTFE hose will find its uses in many industries. Choose white PTFE or static-conducting black tube. Our 5000 PSI and 6000 PSI hoses are made with a post-sintered PTFE tube for low effusion of gases. Available in bulk lengths or complete assemblies with fittings. Various types of testing is also available.

For applications where you require the high-temperature, high-pressure characteristics of flexible metal hose, but also need a smooth-bore PTFE liner, our SF-TSC Series hose will do the trick. Very often used as short flex connectors between chemical tanks and permanent piping, SF-TSC hose assemblies are manufactured with PTFE flared over stainless steel stub ends and backing flanges are 304 or 316 stainless steel.

Series SF-TSC Flexible Metal Hose with Liner

Teflon lined metal hose
Liner:

Smooth-bore, white PTFE flared over metal stub ends

Metal Hose:

Annular corrugated Series 300 stainless steel (321 or 316 available)

Reinforcing:

304 stainless steel braid (316 S/S available) – single or double braid

Temperature Range:

-65 Deg. F. to 350 Deg. F.

Flange Types:

Carbon steel, 304 or 316 stainless – ANSI Class 150 or 300 lb. Flanges rotate.

Applications:

Unisource Series SF-TSC hose utilizes a very specialized construction to create a flexible connector suitable for the most severe applications. Series SF-TSC is constructed using close-pitch, annually corrugated metal hose. A smooth-bore white PTFE liner is inserted into the hose and locked into place. Ends of the PTFE liner are flared over the stainless steel stub retainers that are welded to each end of the hose. This creates a hose connectors with all wetted surfaces being PTFE. Floating flanges rotate behind the tube retainers.

Corrugated metal hose can be either T321 stainless steel or T316 stainless steel. Standard single braid is made of T304 stainless steel. Special T316 stainless steel braid material is available on special order. Floating flanges do not contact the stream flow, and can be constructed of carbon steel, T304 or T316 stainless steel.

Series SF-TSC hose is often used as a short connector between mechanical equipment or tanks and the solid piping system. They are often used to help reduce the effects of equipment induced noise, vibration, or shock, and offset movements caused by seismic activity or equipment settling. Series SF-TSC connectors provide high working pressures, superior corrosion resistance, and moderate flexibility–even at elevated temperatures.
