Standard Duct and Fittings

Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.

Vent Caps


Exhaust Vent	Intake Vent

Cover vents with caps that let air in or out.

Exhaust Vent—A built-in damper allows air to escape while blocking backdrafts, rain, and snow.

Intake Vent—Only fresh air enters though the screen—no debris or pests allowed.

Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.

Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

Pipe Flashings for 40° Shingled Roofs

Use these flashings on plumbing vent pipes and two-walled, air-insulated vent pipes (also known as Type B roof vents). They allow pipes that penetrate your roof to expand, contract, and vibrate without disturbing the watertight seal.

All-Weather Application Sealants

Apply these sealants on wet surfaces and in cold temperatures. They’re non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

Cannot Be Sold To—Sealants that cannot be sold to the regions listed are restricted by local chemical regulations, including limits on VOC (volatile organic compounds).

Pipe Flashings for Corrugated-Metal Roofs

These flashings allow pipes that penetrate your roof to expand, contract, and vibrate without disturbing the watertight seal. Trim the rubber cap to fit a range of pipe sizes. All caps resist water, sunlight, and ozone.

Silicone Rubber Cap—Silicone rubber caps withstand higher temperatures than EPDM caps. They’re often used with gas vents and hot roof pipes for heaters and stoves.

Aluminum Foil Tape

Create permanent, watertight seals for roof flashing, seams, and pipes. An aluminum-foil backing shields the adhesive from UV rays and harsh weather, so the bond stays strong over time. It adheres to virtually any building material, including metal, wood, plastic, concrete, brick, asphalt, and glass.

Self-Fusing Rubber Sealing Tape

Image of Product. Front orientation. Repair and Duct Tape. Self-Fusing, Sealing.

Bonds to itself for a permanent, watertight seal. This tape has no adhesive, so it won't dry out and crack, which can cause standard tape to fail over time. The rubber backing molds to irregular surfaces and withstands demanding conditions, making this tape a good choice for patching and sealing anything from roofs to pipes.

Butyl Rubber—Creates an airtight, impermeable seal. It also stretches and conforms better than EPDM rubber tape.

EPDM Rubber—A good choice for outdoor applications, it withstands sunlight, ozone, and weathering.

Polyolefin/Rubber—Sticks to most surfaces, including vinyl, fiberglass, PVC, wood, tile, and even damp nonporous surfaces.
