Designed to withstand extreme environments, these Viton® fluoroelastomer sealants have excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, gasoline, fuels, and crude oil. They’re non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Self-Leveling Chemical-Resistant Sealants

Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, gasoline, and oil. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Sealants that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).

Reusable Non-Hardening Thread Sealants for Coarse Threads

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads. Threads coated with these sealants can be installed multiple times without recoating. They have low locking strength, so they prevent threads from loosening due to vibration and can be adjusted without tools. They meet NSF/ANSI 61 for use with drinking water.

Non-Hardening High-Temperature Thread Sealants

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. They have low locking strength, so they can be adjusted without tools.

High-Temperature Thread Sealants

These sealants have high locking strength, so they work in demanding applications, such as securing mounting studs in motor housings.

Room-temperature cure sealants must be mixed with water for use; they harden as the water evaporates. Mix about five parts powdered-sealant to one part water to form a thick consistency similar to peanut butter. Hardening can be accelerated with heat; do not heat to above 200° F. They require a hand tool to unthread.

1000° F max. temp. sealants expand as they harden.

1500° F max. temp. sealants are for use on cement-lined pipe joints prior to welding. The heat from the welding torch helps them begin to harden.

Thread Sealants for Oxygen Systems

Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems. They contain PTFE, which provides a slippery surface that keeps threads from binding. These sealants are non-hardening, remaining pliable enough to self-heal and stop leaks before they start, so they’re often used in high-vibration applications that could cause standard thread sealants to fail. Since they have low locking strength, these sealants can be adjusted without tools.

The sealant in a tube is a good alternative to thread sealant tape—like tape, it forms PTFE strings between tightened threads, but excess material liquefies, so it won’t clog system components downstream.

Thread Sealant Tape

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.

PTFE tape with graphite creates a better seal between threads than plain PTFE tape, which helps prevent fluid and gas leaks. The graphite attaches to the PTFE, so this tape does not emit harmful VOCs.

Thread these fittings onto your testing equipment by hand for a secure connection in testing applications—no tools, tape, or sealant required. Use them with gauges and other equipment as a temporary connection. When pressure is applied, the O-ring on the outlet presses against the testing equipment, creating a tight seal.

Adapters with intermittent swivel rotate 360° until tightened for easy installation.

Gauge Guards

316 Stainless Steel Guard

316 Stainless Steel Guard With Drain Port

Also known as isolators or diaphragm seals, these protect gauges from corrosive process media. Fill guards with ISO Grade 32 hydraulic oil (not included) before use.

316 stainless steel guards provide excellent corrosion and chemical resistance and can handle higher temperatures and pressures than plastic guards.

Guards with drain port allow you to remove process media.

Sanitary Gauge Guards

Keeping corrosive substances from touching pressure gauges used in food-processing and pharmaceutical plants, these guards have a sanitary design. Made of 316 stainless steel, they won’t rust from frequent washdowns with harsh cleaners and sanitizers. They have continuously-welded seams and polished surfaces, so there aren’t any pits for bacteria to grow in. Removing them for cleaning and maintenance is easy thanks to their quick-clamp connection, which is sometimes called a tri-clamp.

Also known as isolators and diaphragm seals, these guards have a 316 stainless steel gasket to shield the pressure gauges from corrosion. Before use, fill the guards with fluid such as glycerin or silicone that’s suitable for food contact.
