Why Buy Beverage System Parts from BeverageCraft?

A worn coupler, a stuck regulator or a damaged fitting can quickly take a keg or a beverage line out of service and there is rarely time to wait for a part when that happens.

We carry components for different parts of a beverage system, from basic items like swivel sets, hose barbs and pump fittings to more specialized components like water pressure regulators, carbonator probe and float assemblies, and Nitro Infuser Pro units.

Whether you're kegging at home or running a commercial soda fountain, BeverageCraft offers components for a wide range of dispensing applications, including carbonators and carbonator replacement parts. For combo chiller-carbonator units and a wider range of fountain dispensers, see Carbonators & Fountain Dispensers. For couplers, faucets and towers built for standard bar kegs, see Draft Beer Parts.

We always guarantee top quality, affordable prices and quick delivery options.

Ball Lock vs. Pin Lock: How Cornelius Keg Disconnects Work

Most homebrew and soda kegging setups run on a Cornelius (corny) keg with two posts on top: a gas post and a liquid post. A gas disconnect locks onto the gas post and feeds CO2 into the keg, pressurizing it. That pressure pushes liquid up through a dip tube and out through the liquid post, where a liquid disconnect connects it to the beverage line and, from there, to the faucet.

These corny keg parts - disconnects, posts and swivel sets - are what let you connect gas and liquid lines to that keg.

Ball lock and pin lock kegs use different disconnect designs and the two are not interchangeable:

  • Ball lock disconnects have a collar you pull back to lock or release the fitting. Ball lock gas and liquid posts are similarly sized, so the two are typically identified by color or labeling rather than by fit.
  • Pin lock disconnects use three pins that slide over the post. Pin lock gas and liquid posts are different sizes, so the wrong disconnect simply won't fit.

If you're not sure which type your keg uses, our guide to ball lock vs. pin lock kegs walks through how to tell them apart.

Frequently Asked Questions

What are corny keg parts?+
Corny (Cornelius) keg parts are the fittings that connect gas and liquid lines to a Cornelius keg's two posts - ball lock or pin lock disconnects, replacement posts and swivel sets.
Are ball lock and pin lock disconnects interchangeable?+
No. Ball lock and pin lock kegs use different post designs, so their disconnects aren't interchangeable. Check which type your keg uses before ordering - our ball lock vs. pin lock guide walks through how to tell them apart.
How do I know if my keg is ball lock or pin lock?+
Ball lock posts are similarly sized, so they're identified by color or labeling rather than by fit. Pin lock posts use three pins and come in two different sizes, so the wrong disconnect simply won't fit.
What water filter do I need for an ice machine or beverage dispenser?+
Most commercial ice machines and beverage systems use an inline replacement cartridge, such as our 3M HF60, HF60-S or HF90 filters. The right model depends on your system's flow rate and water quality needs - contact us if you're not sure which one fits your setup.
How often should I replace a water filtration cartridge?+
3M rates these cartridges by total filtering capacity rather than a fixed calendar schedule - replace the cartridge once it reaches its rated capacity or you notice a drop in flow or taste, whichever comes first.
