The Axial Foot Type Combined Seal consists of a foot-shaped sealing ring made of filled PTFE and a rubber O-ring. It is designed for unidirectional static sealing applications, such as axial (end-face) and flange seals. Key features include a long service life, excellent sealing performance, resistance to high and ultra-high pressures, and a compact design that requires minimal installation space; it is also suitable for hydraulic sealing applications. Available in two versions: RC2875-A (for internal pressure) and RC2875-B (for external pressure).
Its compact structure fits into narrow installation grooves, significantly reducing the risk of equipment leakage. A full range of specifications is available in stock, and we welcome inquiries and sample orders from global buyers.

This seal consists of a modified PTFE seal ring with a foot-shaped profile and an O-ring. Under pressure, the seal's gripping force increases—meaning the higher the pressure, the better the sealing performance. Thanks to the slide ring's foot-shaped side flange design, the O-ring is prevented from extruding, allowing the seal to withstand high and ultra-high pressures.
