Interpump KIT377 is the complete 22mm water seal assembly listed for VHT6639. When planning a water-end repair, matching the kit to the pump model matters just as much as matching the size.
Matched pump applications
Kit reference: KIT377
Listed models: VHT6639
What the kit covers
One piston-position assembly with high- and low-pressure seals, intermediate and bottom rings, and the O-ring. Three kits are needed to renew all three piston positions.
Before you order
Inspect the components around the repair area as well as the parts you are replacing. A new kit is not a substitute for identifying damage elsewhere in the assembly. Match the model, kit number and drawing revision to your pump’s identification plate and parts list.
Not sure which kit you need? Send us the pump model and a clear photo of the plate. We can help you identify the right part before you order.
