1. You are buying a pair of re-manufactured neoprene gaskets to the original Lister specification,  These are fitted above and below the brass valve plate on the Lister type 187 domestic pump.These have been professionally made on a commercial press resulting in a high quality accurate reproduction of the originals.  Ideal to get your tired Lister pump working at full output again and prevent annoying water leaks.  Free U.K. p & p and same day dispatch on orders before 12 p.m. excluding weekends and bank holidays.
I also manufacture neoprene valve seals for the Lister pump so whilst you have the pump apart to replace the gaskets why not replace the valve seals  to get your pump working to full output again?
 FULL pump overhaul gasket set now availble including these seals, valve seals and all other paper gaskets for the amazing price of just £24.95 including these gaskets  (see seperate listing )


*****Please see seperate listing where  you can buy both items together (4 valve seals and 2 chamber gaskets ) for a discount price of JUST £15 also including free P&P *******
