Chimney Pipe Brand Guide: DuraVent vs Selkirk vs Metal-Fab

Author: Sean Summers, NFI Master Hearth Certified Technician – WoodstovePro.com

Shopping for chimney pipe can feel confusing fast—especially when you see multiple reputable chimney pipe brands offering similar-looking components. Three of the most common names homeowners encounter are DuraVent, Selkirk, and Metal-Fab. All are widely used, UL-listed manufacturers with strong product lines. The key isn’t finding the “best” brand in a vacuum—it’s choosing the right system for your appliance and making sure every part in the system is compatible.

This guide explains what to know when comparing DuraVent vs Selkirk vs Metal-Fab, how their systems differ, and how to avoid the #1 mistake.

Why brand matters in chimney systems

Chimney systems are tested and certified as complete assemblies. That means a Class A chimney pipe, support boxes, tees, caps, elbows, and adapters are designed to lock together using specific twist-lock or locking band mechanisms unique to each manufacturer.

Even if two pieces look similar, that doesn’t mean they’re compatible. Mixing brands can cause:

• Poor fit and leaking joints
• Failed inspections
• Void manufacturer listings/warranties
• Chimney safety risks over time

So the top rule in all chimney installs: choose a system and stay within that system for all parts.

DuraVent: broad selection and widely supported systems

DuraVent is one of the most recognized names in venting, known for a large lineup across wood, gas, pellet, and special venting applications. Many installers like the availability of parts and clear documentation.

Common reasons homeowners choose DuraVent:

• Wide availability and broad dealer support
• Strong range of chimney and stove pipe solutions
• Lots of component options for complex installs
• Good documentation for sizing and transitions

Best fit for: homeowners who want a commonly stocked system with many configuration options and support components.

Selkirk: long-standing venting manufacturer with popular Class A systems

Selkirk is another major leader in chimney pipe, commonly used for wood stove and fireplace venting. Like DuraVent, Selkirk offers a range of Class A chimney pipe and connector systems, along with a deep accessory catalog.

Common reasons homeowners choose Selkirk:

• Reliable, widely used chimney system options
• Strong history and broad product support
• Good availability for standard and replacement installs
• Robust components for through-the-wall and straight-up installs

Best fit for: homeowners matching an existing Selkirk setup or those wanting a widely recognized, dependable chimney system.

Metal-Fab: heavy-duty construction and strong commercial-grade reputation

Metal-Fab is well-known for high-quality venting and chimney products, often associated with heavier-duty applications and strong manufacturing standards. Many homeowners encounter Metal-Fab when replacing or upgrading systems that were installed by pros, particularly where durability is a priority.

Common reasons homeowners choose Metal-Fab:

• Strong build quality and durability focus
• Excellent option when matching an existing Metal-Fab install
• Trusted in both residential and commercial venting environments
• Solid selection of components for wood and all-fuel systems

Best fit for: homeowners prioritizing robust construction or needing to match an existing Metal-Fab system for compatibility.

The biggest factor: compatibility (aka, don’t mix brands)

When comparing chimney pipe brands, the most important decision isn’t which name you prefer—it’s which system you already have (if you’re replacing parts) and which system your layout requires (if you’re installing new).

If you’re replacing chimney parts

Match:

• Brand
• Diameter
• Product line/series (Class A vs pellet vent vs gas vent)
• Locking method (twist-lock, locking bands, etc.)

A 6-inch pipe from Brand A is not automatically compatible with a 6-inch pipe from Brand B—even if both are UL-listed.

If you’re building a new chimney system

• Choose the brand that best fits:
• Your appliance fuel type (wood, pellet, gas)
• Your vent path (through-the-wall tee vs straight-up support box)
• Local availability for future parts and service

Staying consistent within one manufacturer system is the safest route.

What else to compare when choosing a chimney pipe brand

Beyond brand, compare these practical factors:

1) Fuel type and venting category

Make sure the system is designed for your appliance:

• Wood/all-fuel Class A chimney
• Pellet vent (biomass-specific)
• Gas direct vent or B-vent (depending on appliance)

2) Stainless steel grade and corrosion resistance

Some systems use different stainless grades for inner vs outer walls. If you burn frequently, live in humid/coastal areas, or want maximum longevity, pay attention to liner material.

3) Installation complexity

Certain layouts require more components:

• Wall thimbles and tee supports for wall exits
• Support boxes, firestops, and attic insulation shields for straight-up installs
• Offsets, elbows, and roof flashings for roof penetrations

Quick decision guide

Choose DuraVent if you want broad system options and easy part availability.
Choose Selkirk if you want a widely used system with strong support and straightforward installs.
Choose Metal-Fab if you want heavy-duty build quality or need to match an existing Metal-Fab system.

The best choice is the one that fits your appliance and ensures full system compatibility from stove collar to chimney cap.

Final thoughts

All three brands—DuraVent, Selkirk, and Metal-Fab—are respected chimney pipe brands. The most important thing is not mixing systems. Confirm your appliance requirements, choose the correct venting category, and build the chimney using components designed for cross-part compatibility within the same product line.
