The FDB seal is made of a helical wound spring and a polymer jacket, It is the best choice for vacuum, gas and low-temperature flange sealing applications.

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.

Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.

Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.

V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.
