Description
The Techcon P3022VPK dispensing valve parts pack supplies replacement Viton O-rings for 30cc and 55cc receiver head assemblies. This 10 count pack is used when a time-pressure dispensing setup needs the receiver head seal refreshed without replacing the full air hose assembly. The listed size is 17.5 mm inside diameter by 2 mm cross section, which should be matched exactly during maintenance.
Where these dispensing valve parts fit
Receiver heads connect pneumatic dispensers to syringe barrels so air pressure can move material through the barrel and tip. The O-ring seals that interface and helps keep air from escaping around the head. A worn or wrong-size seal can show up as weak pressure response, inconsistent bead size, bubbling, or extra adjustment at the controller. Use this Viton version when the approved setup calls for the 30cc or 55cc receiver-head seal rather than a smaller 3cc, 5cc, or 10cc size.
Viton is a fluoroelastomer sealing material often selected for tougher fluid exposure than standard EPR. Compatibility still depends on the adhesive, solvent, cleaner, and temperature in the actual station, so confirm the seal material against the maintenance procedure before installation. Keep replacement packs labeled by syringe size and material so small seals are not mixed during a quick rebuild.
How this O-ring supports receiver head service
Replace the O-ring when it is cut, flattened, swollen, cracked, or no longer sealing cleanly. Clean the gland before installation, avoid sharp picks that can nick the new seal, and test the dispenser with the intended fluid or approved setup material before changing dispense time or pressure. The right seal lets the operator solve the root leak instead of chasing controller settings.
