Custom waterproof rubber seal stoppers/EPDM pipe plugs

EPDM pipe plugs fit matching pipe openings where the selected rubber and geometry must suit the actual service. The direction of any pressure difference affects how the closure is retained, so sealing contact and resistance to displacement should be considered together. A plug fitted for temporary debris protection should not be treated as a pressure closure without a suitable complete design.

Check the pipe bore, usable depth, and entrance condition. Include any ovality or damage at the cut end that may interrupt contact. Select the EPDM compound around the medium, temperature, and cleaning exposure, then evaluate the completed closure under its relevant conditions.

Insert the plug in line with the pipe and preserve the intended access for removal. Keep residue and sharp edges away from the rubber contact band. Before removing a plug from operating equipment, place the system in the appropriate condition for safe opening. Inspect the part after removal for cuts or persistent deformation, and correct a damaged pipe seat before installing a replacement.

Material options

Solid rubber options: 30–90 Shore A. The direction of any pressure difference affects how the closure is retained, so sealing contact and resistance to displacement should be considered together.

Custom geometry

Check the pipe bore, usable depth, and entrance condition.

Fit evaluation

Include any ovality or damage at the cut end that may interrupt contact.

Color & OEM
