Firestone Keg Ball Lock Posts (NEW)

Ball Lock Post Set - Firestone Keg - NEW

Upgrade your Firestone keg with this brand-new set of ball lock posts, designed specifically for Firestone models. Each set includes new poppet valves and fresh post o-rings, fully assembled and ready to install.

Crafted from durable 304 stainless steel, these posts are built for long-term performance.

They are compatible with standard ball lock Firestone V Challenger, Firestone VI Challenger, and Firestone Super Challenger kegs. Not compatible with Cornelius kegs.

Installing the new posts is simple: remove your old Firestone posts (a proper keg-post socket is recommended), clean the keg’s threads to ensure a solid seal, and thread the new posts into place. Since the posts come preassembled with o-rings, they can be installed immediately. While the posts are off, it’s wise to pull the dip tubes and replace the dip-tube o-rings—especially on older kegs—to help prevent any leaks below the posts.

Remember that Firestone-style corny kegs use two different thread sizes, meaning the gas and liquid posts are not interchangeable. This differs from Cornelius kegs, where both posts share the same thread size.

Note: These posts cannot be used to convert a pin-lock Firestone keg into a ball-lock keg.

Firestone Keg Post Specs:

• Gas - 9/16"-18 Threads
• Liquid - 5/8" -18 Threads
• Material: 304SS
• Poppets and o-rings included
