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.

Use color to identify water, gas, and chemical connections. 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.

Green tape is often used for oxygen.

Orange and yellow tape is commonly used to indicate fuel and gas.

Red tape is often used for water.

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.

Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to harsh chemicals. 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.

Viton® fluoroelastomer sealants resist sulfuric acid, hydrochloric acid, nitric acid, gasoline, fuels, and crude oil.

Aflas fluoroelastomer sealants stand up to hydroxides, industrial cleaning fluids, and other pH-basic chemicals in applications where traditional rubber caulk is ineffective.

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).

Use these fittings to connect welding hose to pressure regulators and torches. They are also known as CGA (Compressed Gas Association) fittings. Fittings are brass for good corrosion resistance.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

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.

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.
