Small O-Rings for Pipe Joints: Confirm Sealing Location and Assembly Clearance

Confirm ring seating and protect it from sharp edges during assembly. AS568 describes dimensions, while joint pressure capability depends on the complete gland and compound. Sour-gas and decompression duties require separate compound qualification. Our ISO 9001 quality management supports specification review and inspection.

Small black rubber O-rings for oil-pipe connection enquiries are specified by the actual joint and sealing groove. Provide inside diameter, cross-section and tolerances, plus a joint drawing or exact size reference. NBR, FKM, HNBR and EPDM require separate compound selection; black colour does not identify the material or establish oil compatibility.
