Seal & Gasket Kit, Becker U 4.100 / U 4.70 / U 4.70 D

This is a complete set of every gasket, O-ring, sealing ring, and valve washer used inside the Becker U4.70 and U4.100 pumps .

Think of it as the complete set of seals for your pump. You get all the parts that prevent leaks.

This is not a Major Overhaul Kit. That kit includes bearings and vanes. This is a Gasket Set. It focuses on one thing and one thing only: replacing all gaskets and seals .

The Becker website confirms: “This Gasket Set allows you to change all gaskets and seals included in a U4.70/100” 

This kit is made for Becker U4.70 and U4.100 pumps .

It fits a very wide range of models and Index variations:

For U4.70 pumps:

• U4.70 (Index A through I) 

• U4.70D, U4.70E, U4.70F, U4.70G, U4.70H
