These flanges are for low-pressure applications in noncorrosive environments.

The galvanized finish on these Pressure Class 150 flanges provides fair corrosion resistance.

Combine an adapter with a two-piece pipe flange (sold separately) to build a customized flange connection for noncorrosive environments.

With better strength than our low-pressure steel flanges, these are for use in medium-pressure applications.

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

Also known as Code 61 SAE hydraulic flanges.

Also known as ANSI flanges.

Also known as Code 61 SAE hydraulic flanges, these let you create an access point in a high-pressure hydraulic line.

Use these heavy duty forged flanges for high-pressure applications.

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Use these unthreaded flanges in low-pressure applications. Also known as Pressure Class 125 flanges.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Bolt two same-size flanges together with a gasket to create an access point within a line. Made of PTFE, they can handle a wider temperature range than any of our other plastic pipe flanges for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges meet UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. They are PVDF, which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Pressure Class 150 flanges.

Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket to create an access point within a line.

Bolt two same-size flanges together with a gasket to create an access point within a line. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

The smooth finish inside these stainless steel quick-clamp fittings makes it easy to remove product residue.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

Quickly connect and disconnect hose lines used with a variety of chemicals, from adhesives to isopropyl alcohol and ink. Any part of these couplings that contacts fluid is made from 316 stainless steel, C-276 Hastelloy, PTFE, or fluoroelastomer to withstand the chemicals in your line.

Aramid fibers are blended with SBR rubber to resist inert gases. These gaskets also resist abrasion.

Furnished with plastic sleeves and washers to provide a layer of protection against dielectric corrosion, which occurs when different metals are joined.

Reinforced with a stainless steel insert, these gaskets are stronger and can hold their shape better than gaskets without an insert.

Form a seal even under the low torque needed for fiberglass flanges. Also known as Gore UPG, these gaskets are made from soft expanded PTFE.

A fiberglass filler in these PTFE gaskets provides strength to prevent them from thinning out when compressed.

Made of Buna-N rubber, these gaskets compress to ensure a tight seal. They resist oil, water, and salts.

The included plastic sleeves and washers provide a layer of protection against dielectric corrosion, which occurs when different metals are joined.

Our highest temperature gaskets, these are made of vermiculite to withstand temperatures up to 1800° F.

Able to withstand temperatures up to 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi.

A stainless steel insert in these PTFE gaskets adds strength and makes them reusable.

Reinforced with fiberglass filler for strength, these PTFE gaskets won't thin out when compressed.

Often used with fiberglass flanges where you want to avoid overtightening, these gaskets seal under low torque. They’re made of soft, expanded PTFE that is also known as Gore UPG.

Also known as Gore GR.

Create a tight seal on grooved-end pipe fittings that are exposed to oil. These gaskets are Buna-N, so they won't break down from oil.

In addition to oil, these blended aramid fiber/Buna-N rubber gaskets resist water and aliphatic hydrocarbons such as ethylene.

These gaskets are made from a blend of graphite and Buna-N rubber to withstand temperatures up to 650° F.

Able to withstand temperatures up to 750° F, these graphite gaskets have a stainless steel insert for strength to handle pressure up to 1,000 psi.

A space between the outer ring and the sealing element prevents the element from being squeezed inward and contaminating the process line.

Instead of bolt holes, these gaskets have tines that easily fit around flange bolts to ensure they’re properly aligned with pipe openings. The tine design also means you won’t have to retorque the flange for alignment, saving time.

These gaskets have a carbon steel outer ring and a 304 stainless steel inside sealing element with a PTFE filler that’s virtually chemically inert. They're also known as spiral-wound gaskets.
