Description
The Techcon P3015EPK dispensing valve parts pack contains 10 EPR O-rings for 3cc receiver head assemblies. This seal size is listed as 6 mm inside diameter by 2 mm cross section. Use it when a small syringe dispensing station needs the receiver head resealed and the maintenance procedure calls for the EPR version rather than a Viton seal.
Where these dispensing valve parts fit
A receiver head is the connection between the dispenser air line and the syringe barrel. It lets controlled air pressure act on the piston or fluid surface, which is what produces repeatable dots and beads. The O-ring seals the receiver head to the barrel interface. When that seal is worn, dirty, cut, or the wrong material, the station can lose pressure, respond slowly, or force the operator to raise settings to maintain the same shot size.
The 3cc size is common in fine assembly work where smaller barrels keep material waste down and allow close hand control. Keep this pack separated from 5cc, 10cc, and 30cc seals because the dimensions are close enough to confuse during a busy bench repair but different enough to affect performance. The EPR material is used across many dispensing applications, but compatibility should always be checked against the adhesive, coating, cleaner, and process fluid.
How this EPR seal supports service work
Replace the O-ring during planned service or whenever it shows swelling, flattening, cuts, cracks, or contamination. Clean the receiver head groove before installing the new seal, lubricate only when the equipment procedure allows it, and avoid metal tools that can mark the O-ring surface. After the repair, test the dispenser with the qualified fluid and tip before adjusting dispense time or pressure.
