4" White Nitrile Clamp Seal Gasket

The G400N serves as the sealing element between compatible grooved pipe or fitting ends. Once positioned correctly, the surrounding clamp keeps the connection mechanically engaged while the gasket seals the joint.

Proper gasket placement is important before the clamp is tightened. The seal should remain centered around the mating ends and free from folds, twists, or trapped debris.

Dixon identifies the white nitrile rubber option for dry-bulk food applications in its grooved clamp product family. The material differentiates this gasket from the black nitrile, FKM-B, and Baylast™ seal options used elsewhere in the family.

Selection should be based on the actual service requirements of the system. Confirm that white nitrile is the required gasket material before replacing an existing seal.

Dixon lists the 4" DBV-WB400 aluminum grooved bolted clamp with a white nitrile rubber seal. The G400N is the corresponding 4" replacement gasket listed in Dixon's replacement-gasket table.

Replacing only the gasket can keep the existing clamp body in service when the clamp components remain in acceptable condition. Inspect the clamp halves, bolts, nuts, and grooved ends before reassembly.

Before installation, clean the mating pipe ends and gasket seating area so dirt or product residue does not interfere with the seal. Inspect the gasket for cuts, hardening, deformation, or other visible damage.

After assembly, verify that the gasket remains evenly seated and that the clamp is fully engaged in both grooves. The completed joint should be inspected before the piping system is returned to service.
