Description

This Repair Kit is an OEM part from Yamada that will fit our 1" Yamada Diaphragm Pump and includes replacement diaphragms, balls and O-Rings.

We only sell the Buna-N materials of this replacement kit which is a great material for the sealcoating industry because it holds up well to coal tar, asphalt emulsions and most importantly aggregates like sand.

Material

We sell the "Buna-N" material in this replacement kit which we've found to do a great job with asphalt emulsion and coal tar sealers, and the Buna N holds up great with sealers that have abbrasives.
