Roof Pipe Gaskets

Roof Pipe Gaskets for Corrugated-Metal Roofs

Trim the rubber cap to fit a range of pipe sizes.

Roof Pipe Gaskets for Single-Ply and Built-Up Roofs

Trim the rubber cap to fit a range of pipe sizes.

Roof Pipe Gaskets for 40° Pitched Shingle Roofs

Use these gaskets on plumbing vent pipes and two-walled, air-insulated vent pipes (also known as Type B roof vents).

Ductwork and Louvers

Flat Roof Vent Caps

Sloped Roof Vent Caps

Gas Chimney Vents and Fittings

For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.

High-Temperature Chimney Vents and Fittings

Built to withstand temperatures up to 1000° F, these vent pipes and fittings are for use with boilers, furnaces, stoves, and other equipment that is fired by coal, gas, oil, propane, or wood.

Fastening and Joining

Rubber Sealing Tape

Patch and seal roofs, window frames, gutters, and vents with this conformable tape.

Aluminum Flashing Tape

Use this tape for a watertight bond on gutters, roofing membranes, and other building materials.

Sealing Tape for Large Gaps and Voids

An alternative to caulk and rubber sealants, this tape comes compressed and gradually expands to fill large gaps and voids.

Foam Sealing Tape

Stop water penetration with this tacky, flexible tape. It conforms to irregular shapes and expands to fill gaps. Use it on freezers, windows, and in marine applications.

UL-Printed HVAC Tape

For easy identification, this tape is printed with flexible duct standard UL 181A-P or UL 181B-FX.

Reinforced HVAC Tape

Reinforced with fiberglass, this tape is flexible yet resists tearing. Use it for sealing and patching insulation and duct.

Foil HVAC Tape

Seal foil-jacketed insulation as well as air-conditioning and refrigeration systems with this conformable aluminum tape.

Shim Stock

Cut this stock into custom shapes to fit your application.

Shim Stock Sets

Keep shim stock in a variety of thicknesses on hand with these sets. Cut into custom shapes to fit your application.

Copper

Multipurpose 110 Copper Sheets and Bars

Offering high electrical conductivity and formability, 110 copper is 99.9% pure. Also known as ETP copper, it's often used in electrical applications, such as for bus bars and wire connectors, as well as for flashing, gaskets, and rivets.

Super-Conductive 101 Copper Sheets and Bars

With 99.99% copper content, 101 copper has higher purity than 110 copper, resulting in superior electrical conductivity. It's commonly called OFE and OFHC copper. Use it in electrical applications, such as for coaxial cables and terminal lugs.
