Internal Assembly kits are the easiest way to rebuild your Push Pull Valves. The old internal assembly is simply removed, and then replaced with the new one. Repair kits are available when all you need to replace is just the “Sealing” mechanism at the bottom of the shaft. Parts are also available if you have one of the older style valves. Contact the parts department for further information on these. Kits come complete with all parts necessary for any facet of the repair.
