This listing is for the Replacement Cup Seals for the Gast 120R Pump. 

Save $$$$ by only replacing these Main Wear components vs the whole kit. The Cup seals wear out over time and are typically the only part that requires replacement.  The cylinders can be cleaned with alcohol and a scotch pad and reused numerous times even if deeply scored.

  Replacing these components returns your unit to original factory performance Pressure specifications. Recommend for service every 2 years. 

Includes (2) cups Seals ONLY as pictured. Does NOT include any other parts, pieces, or the pump itself.

If you have low pressure or Vacuum this kit will correct that when correctly installed.
