Dayton PPL3430G Buna-N Casing Gasket

This Buna-N O-ring casing gasket fits Dayton turbine pumps listed by Grainger part numbers 4JPF3, 4JPF5, 4JPF8, 4JPF9, 4JPG1 and 4JPG2. It provides a replacement seal for the pump casing in compatible industrial or commercial plumbing systems.

Thermals noise and power draw

The gasket is a static sealing component and does not generate heat, produce noise or draw electrical power during pump operation. Its material resists degradation from fluid contact within normal service conditions.

What the bundled items change

The package includes the casing and O-ring together so the mating surfaces are replaced as a matched set. No additional hardware, lubricant or installation tooling is supplied with this part.

Questions about this item

How do I install the Buna-N O-ring casing gasket on my Dayton turbine pump without pinching it?

Lubricate the Buna-N O-ring with compatible grease, seat it evenly in the casing groove, then torque the casing bolts in a cross pattern to avoid pinching the gasket during reassembly.

When should I replace the Buna-N gasket on my Dayton turbine pump?

Replace the Buna-N gasket whenever the pump casing is opened, or at each scheduled seal service interval, because the material takes a compression set and cannot be reused reliably.

What is the first sign the Buna-N gasket is failing under continuous pump operation?

A weep of liquid at the casing joint appears first, signalling the Buna-N O-ring has lost elasticity and can no longer maintain a seal under sustained pressure.
