Description
The Wunder-Bar EPDM Interconnect O-Ring is a critical replacement seal for the main manifold connections of commercial soda bar guns. This specialized O-ring (PM10-14-E) ensures a high-pressure, liquid-tight seal between the input fittings and the gun body. Constructed from high-durability EPDM, it is designed to withstand the constant pressure and acidic nature of soda concentrates for long-term reliability. Replacing this seal is the first step in fixing “handle leaks” in standard Wunder-Bar post-mix systems.
Technician’s Repair Tip: If your soda gun is leaking at the point where the hose bundle enters the handle, the interconnect O-rings are likely failed. When performing a full gun rebuild, always replace all input O-rings simultaneously. Lubricate the new seals with food-grade silicone grease (Haynes Lubri-Film) to ensures they seat perfectly and do not bunch or tear during reassembly.
