Porous PTFE Film

Color: White
Maximum Temperature: 500° F
Specifications Met: UL 746C, UL 94 V-0

Shield vents on electronic and automotive equipment, such as cell phone microphones, from water, dirt, and debris without blocking them entirely. This film has tiny holes to let air, gas, and vapors pass through. Because it’s made of PTFE, it wicks away water. It also won’t react with most chemicals, though it can break down from alkali metal and high-temperature fluorinated agents. IP rated, this film stands up to dust, weather, washdowns, and even brief submersion.

Porous PTFE Adhesive-Back Discs

Color: White
Maximum Temperature: 250° F

Stick these discs onto breather and other circular vents to guard against water and dirt without obstructing flow. Often used in the electronic and automotive industries, they have very small holes so air, gas, and vapor can still pass through. These discs are made of PTFE to wick water away. They also won’t break down from most chemicals, except alkali metal and high-temperature fluorinated agents.

IP rated except for their adhesive, all seal out dust and stand up to some submersion. IP65-rated discs also handle low-pressure washdowns, while IP66-rated discs withstand high-pressure washdowns.

PTFE-Coated Fiberglass Mesh Fabric Sheets

With larger openings than porous fiberglass fabric, these sheets allow for more air circulation in drying applications. The PTFE coating makes them nonstick and chemical resistant.

High-Temperature Expandable Sleeving

Protect cable, hose, and pipe from abrasion and cuts in high temperature environments—this sleeving withstands temperatures over 450° F. It expands to fit over items for easy installation; sleeving then tightens around its contents for a secure fit. The braided construction permits heat and moisture to dissipate.

PTFE and PEEK sleeving withstand chemicals and salt water, so they can be used in extreme environments where cable and hose need protection from harsh fluids, such as in chemical plants and in oil and gas production. It has better abrasion and tear resistance than fiberglass sleeving. PTFE sleeving also withstands acids and solvents. PEEK is lighter in weight than PTFE, and more cost efficient.

Ultra-Chemical-Resistant PTFE Gaskets with Screen for Quick-Clamp Tube Fittings

Offering excellent resistance to detergents, hydraulic fluid, and salts, these PTFE gaskets have a corrosion-resistant 316 stainless steel screen to provide inline straining. They also have good resistance to most acids and alkalies. Use them to ensure a tight seal in quick-clamp stainless steel sanitary tube fittings. The mesh size indicates the number of openings on the screen per square inch.

Ultra-Chemical-Resistant PTFE Gaskets with
Perforations for Quick-Clamp Tube Fittings

These chemical-resistant gaskets have a perforated plate that filters, separates, and strains liquids or dry materials in your line. Made of 316 stainless steel, the plate won’t corrode from frequent washdowns with harsh cleaners. Gaskets are made of PTFE for excellent resistance to detergents, hydraulic fluid, and salts, and good resistance to most acids and alkalis. They create tight seals in quick-clamp sanitary tube fittings. These gaskets are 3-A certified for sanitary design and are FDA compliant for direct contact with food. They meet ASME BPE purity and safety standards, and are rated USP Class VI as plastic that won’t leach into biological samples.
