Draft Beer Fittings & Replacement Parts – All Types & Sizes
This is the small-hardware backbone of a draft system — the fittings, barbs, splices, clamps, and tailpieces that connect beer line, CO2 line, and glycol hose to everything else. If you're troubleshooting a leak, replacing a worn part, or building a kegerator from scratch, this is where the connectors live.
- Barb Fittings – For securing beer line and gas tubing to couplers, faucets, and regulators
- MFL Flare Fittings – Standard male flare lock fittings for CO2 and gas line connections
- Threaded Connectors – NPT and BSP threaded fittings for gas and liquid applications
- Glycol Hose Fittings – Compatible with polyethylene and barrier glycol tubing
- Clamps & Crimpers – Stepless Oetiker clamps, worm-drive screw clamps, and the crimping tools to install them
- Splices, Tees & Y-Bends – For joining, branching, or reducing line size mid-run
Matching Fitting Size to Your Line
Fittings are sized by barb OD to match your tubing's ID — a 3/8" barb fitting is for 3/8" ID beer line, not 3/8" tubing OD. If you're not sure what size line you have, measure the inside diameter where it slides over a barb, or check the spec sheet for your coupler, faucet, or shank.

Fittings FAQ
How do I know what size fitting I need?
Match the fitting's barb size to your tubing's inside diameter (ID), not the outside diameter. If you're replacing an existing fitting, measure the old one or check the tubing spec; if you're not sure, send us a photo or the tubing size printed on the line and we'll confirm before you order.
Barbed fitting or compression fitting — what's the difference?
A barbed fitting pushes into the tubing and relies on a clamp to hold the seal — the standard for beer and gas line. A compression fitting uses a nut and ferrule to grip the tubing without a separate clamp, common on rigid or semi-rigid tubing and some CO2 connections. Use whichever your existing line and coupler are already set up for; mixing types usually means replacing more than just the fitting.
Do I need stainless steel fittings, or is brass or plastic fine?
Stainless steel is the standard for commercial draft systems — it resists corrosion from beer, CO2, and cleaning chemicals over years of daily use. Brass and plastic fittings show up in lower-cost or home kegerator kits, but for a bar or restaurant running daily cleaning cycles, stainless is worth the extra cost.
What's a hose splice or a Y-bend actually used for?
A splice joins two lengths of the same-size tubing into one continuous run, or steps between two different sizes. A Y-bend (or tee) branches a single line into two — common when running one CO2 supply to multiple regulators or splitting a cleaning line to reach two faucets at once.
