About Sealant Flexibility
More
Chemical-Resistant Sealants

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.
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. For high-wear applications, choose a harder sealant for the most abrasion resistance.
Sealants that cannot be sold to the regions listed exceed local regulatory limits on VOCs (volatile organic compounds).

Non-Hardening Thread Sealants with PTFE


PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, 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.
To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
VOC (volatile organic compounds) regulations restrict sales of sealants that cannot be sold to the listed jurisdictions/areas.

Thread Sealants with PTFE

PTFE provides a slippery surface that keeps threads from binding. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.
Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

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.
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.
Reusable Non-Hardening Thread Sealants for Fine Threads

Formulated to flow into small spaces, use these sealants between fine 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.

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.
High-Density Thread Sealant Tape

This tape has a higher density than standard tape for a better seal between threads. Made of PTFE, it has a slippery surface that keeps threads from binding to make parts easy to assemble.

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 Sealant Tape for Stainless Steel Threads

This tape contains nickel to prevent seizing and galling associated with stainless steel threaded connections. It’s also good for use with other metals. This tape has a higher density than standard tape for a better seal between threads. Made of PTFE, it has a slippery surface that keeps threads from binding to make parts easy to assemble.

Gauge Guards


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.
