Durable Materials You Can Trust

Our specified gas piping products are made from materials such as high-quality stainless steel and/or coated corrugated tubing, providing corrosion resistance and dependable performance under high temperatures. Whether you're connecting a direct-vent gas fireplace, a freestanding gas stove, or outdoor gas insert, the right components make all the difference in system safety and longevity.

What Does a Stove Pipe Elbow Do?

A stove pipe elbow is essential for navigating tricky spaces and safely redirecting venting in your gas stove or fireplace installation. These angled connectors allow you to change the direction of your gas vent run - perfect for routing around joists, beams, or other obstacles in your home. By providing flexibility in your venting layout, elbows help your system maintain proper clearance and performance, all while supporting a safe and secure installation. Choose from a variety of sizes and angles to fit your specific venting needs, ensuring both efficiency and peace of mind.

Concentric Flex Pipe: Versatile Venting for Gas Appliances

If you're looking to vent your gas fireplace or stove through spaces where rigid pipe just won't fit, concentric flex pipe offers the flexibility and safety you need. This uniquely designed pipe features a "pipe within a pipe" construction - allowing one passageway for exhaust gases while the other draws in fresh combustion air from outside.

Why does this matter? With concentric flex venting:

• You maintain a sealed system – Prevents indoor air from mixing with combustion, supporting clean operation and stable flame.
• Easier installations in tight spots – The flexible design adapts to curves, offsets, and obstacles that traditional rigid venting can't handle.
• Supports both vertical and horizontal runs – Perfect for retrofits or challenging architectural layouts.

Commonly used with direct-vent gas fireplaces and stoves, concentric flex pipe is available in various length and diameter combinations (like 4" inner x 6-5/8" outer) to match your specific appliance requirements and building codes.

What Is a Pipe Extension and Why Might You Need One?

A pipe extension plays an important role in gas stove venting systems. If the standard vent pipe isn't quite long enough to reach from your appliance to the termination point, a pipe extension gives you the extra length you need - without compromising safety or efficiency.

For example, an 8-1/2" extension can help bridge gaps in your venting run, whether you're routing through a thick wall, ceiling, or simply need a little more reach to make all your connections line up. Extensions are made to work seamlessly with other venting components, ensuring a tight seal and proper exhaust flow.

When selecting an extension, be sure to match the diameter and material (such as galvanized steel or stainless steel) with your existing vent system. Brands like DuraVent, Metal-Fab and Selkirk offer a variety of compatible lengths so you can find the perfect fit for your installation. Proper sizing is key for both safety and appliance performance.

Storm Collars: Protecting Your Chimney System

A storm collar is a simple but critical component used in venting installations. Designed to sit snugly around the chimney pipe just above the flashing, a storm collar prevents rain, snow, and debris from entering the ventilation system through the roof penetration.

For example, a 3-inch diameter storm collar - like those offered by trusted brands such as DuraVent - features a corrosion-resistant metal construction that seals out the elements and keeps your system operating safely year-round.

Key benefits:

• Shields the interior of your home from moisture
• Prevents leaks that can damage insulation and framing
• Compatible with most gas stove, fireplace, and water heater vent installations

What Does a Stove Pipe Rain Cap Do?

A stove pipe rain cap is a small but vital accessory that helps protect your venting system from the elements. Installed at the top of your gas stove or fireplace vent, it acts as a shield against rain, snow, and debris - preventing unwanted moisture or blockages from entering the pipe. This not only extends the life of your system by guarding against corrosion, but also helps maintain optimal airflow and performance. For anyone installing or maintaining a gas appliance, adding a quality rain cap means extra peace of mind and added durability for your venting setup

Whether you're working with rigid lengths, flexible extensions, elbows, flashings, or specialty termination caps, you'll find a comprehensive selection here for new installations or repairs. All items are designed for durability and easy compatibility with modern gas appliances, ensuring safety and efficiency for your venting system.

What Is Adjustable Flashing - and When Do You Need It?

Adjustable flashing is an essential finishing piece for your stove pipe installation, designed to create a weatherproof seal where your vent or chimney passes through a sloped roof. Unlike fixed flashing, adjustable flashing is built to flex or adapt to roofs with varying pitches - making it a one-size-fits-most solution for both mild and steeper slopes.

When might you need adjustable flashing for your stove pipe setup?

• When your stove pipe or vent is routed through an angled section of your roof.
• If you anticipate future roof work that could alter the roof pitch.
• For installations where stock or rigid flashing just won't provide a snug, reliable fit.

Relying on adjustable flashing helps protect your home from leaks and the intrusion of debris, rain, and even the occasional snowdrift.
