Black Rubber O-Rings for Water Sealing — Compound and Gland Selection

Black circular-section O-rings are selected by inner diameter, cross-section and gland dimensions. NBR, EPDM, FKM and silicone are separate compound options; black color alone does not identify the polymer or establish suitability for water exposure. Specify the required compound and hardness with the size reference.

For water-sealing enquiries, provide water temperature, treatment chemicals, exposure duration and whether the seal is static or moving. Define operating pressure, mating surfaces and the required leakage test. Review the selected compound and gland together before specifying a seal; a general waterproof description does not establish an enclosure rating or drinking-water approval.
