Wunder-Bar & Taprite bar gun and soda gun parts
Keep your post-mix bar guns and soda guns pouring with genuine replacement parts for Wunder-Bar, Taprite, Multiplex, and compatible systems. This catalog covers the full wear-and-tear list a working bar runs through — button caps and ID caps, nozzles and diffusers, diaphragms, O-rings and seals, syrup lines, triggers and levers, holsters and hangers, drip cups, and complete rebuild kits. Whether you run a single gun behind one bar or service dozens across an account, you can match the exact part instead of replacing the whole gun.
Match by OEM part number — built for service techs
Every listing carries the manufacturer part number (PH-, PM-, FR-, and 12Q- series for Wunder-Bar and Taprite) so field techs can cross-reference a worn component in seconds. Know the series before you order: Wunder-Bar guns run across Series II, Series 2.5 & III, and Mark 4 (M4), and nozzles, diffusers, and manifolds are not always interchangeable between them. If you are not sure which generation you are working on, the interactive Mark 4 parts diagram on our Bar Guns page maps each callout to the matching part.
Soda gun buttons, caps & flavor ID
Flavor button caps are the most-replaced part on any soda gun — they crack, fade, and get swapped as menus change. We stock round and oval snap-on ID caps in the standard flavor set (Coke, Diet, Sprite, water, soda, tonic, and more) plus blanks, in both Wunder-Bar and Taprite fitments. Buy the single cap you need or a full set to re-label a gun.
Bar gun & soda gun parts — FAQs
What soda gun parts do you carry?
Button caps and ID caps, nozzles and diffusers, diaphragms, O-rings and seals, syrup lines, triggers, holsters and hose hangers, drip cups, input manifolds, and complete rebuild kits for Wunder-Bar, Taprite, Multiplex, and compatible bar guns.
How do I know which Wunder-Bar series my gun is?
Wunder-Bar guns fall into Series II, Series 2.5 & III, and Mark 4 (M4). The series is usually marked on the gun body or manifold. Nozzles, diffusers, and manifolds differ between series, so confirm yours before ordering — the Mark 4 parts diagram on our Bar Guns page shows each component by callout number.
Are these genuine Wunder-Bar and Taprite parts?
Yes — we stock OEM Wunder-Bar and Taprite components, listed by manufacturer part number so you can match the exact part you are replacing.
Do soda gun button caps fit both Wunder-Bar and Taprite guns?
Most round and oval snap-on ID caps share fitment across Wunder-Bar and Taprite guns, but check the individual product listing for the specific fitment and shape (round vs. oval) before ordering.
How fast do parts ship?
Most in-stock parts ordered before 2pm CT ship the same business day.
