Metal Products

Finish round ductwork the right way with take-off tab collars, splice collar duct couplings, metal reducers, metal 90 adjustable elbows, metal wye Y-fittings, snap lock pipe, and drain pans, stands, line covers, and more. These components are ideal for fabricating and joining round metal duct, transitioning sizes and angles, branching supply runs, extending runs with snap lock, collecting condensate, and protecting/covering line sets in tight spaces.

Made for DIY-capable homeowners, licensed contractors, property managers, and light commercial crews, this lineup delivers dependable performance without the premium price tag. With heavy inventory on core sizes and parts priced from just a few dollars up to about $110, you can outfit the whole job-start to finish-on budget.

Common residential diameters include 4-8 inches (with 8-10 inches for trunks); choose gauges from 30-26 ga galvanized steel, and heavier where code or span requires. These sheet metal components are system-agnostic: they pair with any SEER2 rating, BTU or tonnage capacity, single- or multi-stage equipment, and common refrigerants such as R‑410A or R‑454B. For best results, use wyes for smoother splits, set elbows to the longest possible radius, fasten with three sheet-metal screws per joint, and seal seams with mastic or UL 181 aluminum foil tape.

Frequently Asked Questions

  • What sizes of snap lock pipe and fittings are typically used for residential duct runs?

    Most homes use 4-8 inch branches with 8-10 inch trunks. Final sizing should follow Manual D or a contractor’s design.

  • How do I choose between a wye fitting and a 90-degree elbow for airflow and static pressure?

    Use a wye when splitting airflow to reduce turbulence. Use elbows to change direction; favor long-radius or two 45s when possible.

  • What is a take-off tab collar and how is it installed on existing ductwork?

    It’s a collar with bendable tabs. Cut the trunk opening, insert the collar, bend tabs tight, add screws, then seal and connect your branch.

  • When should a metal reducer be used and how do I size it correctly?

    Use reducers when transitioning diameters to meet airflow targets. Step down 1-2 inches at a time to limit noise and pressure loss.

  • Are these metal duct components suitable for light commercial HVAC applications?

    Yes. Choose heavier gauges (26-24 ga where required), larger diameters as needed, proper supports, and verify local code compliance.

  • What materials or gauges are common for these metal fittings and are they compatible with existing duct systems?

    Galvanized steel in 30-26 ga is most common. These components integrate with standard round metal duct and many mixed systems.

  • Do I need sealant or tape with splice collar couplings, and which type is recommended?

    Yes. Use water-based mastic or UL 181 aluminum foil tape and three screws per joint. Seal both the joint and longitudinal seams.

  • Which drain pans and line covers fit standard residential air handlers or coils?

    Match the pan to the unit’s footprint and secondary drain needs. Line covers in 3 or 4 inch channels fit most residential line sets.

  • Can adjustable elbows lock at specific angles?

    Most 90 adjustable elbows set anywhere from 0-90°. Space the seams evenly, secure with screws, and seal the joints after positioning.

  • Are these parts compatible with any SEER2 rating or refrigerant type?

    Yes. Sheet metal fittings are rating- and refrigerant-agnostic, working across all SEER2 levels, BTU/tonnage, and common refrigerants.
