Frequently Asked Questions

The ring acts as a sealing component — it closes internal fluid‑housings tightly and prevents leaks or pressure loss in pumps or fluid assemblies.

Not recommended. OEM packing ensures correct dimensions and groove fit — generic ring may cause leaks or improper sealing under pressure.

Typically used in diaphragm pumps’ fluid section covers, internal housings, or any assembly that originally shipped with 115055 square‑ring packing. Refer to your pump’s manual or parts list.
