Quad-Rings are double-acting, 4-lobed seals with a square cross-sectional seal profile. These seals are direct retrofit to O-Ring type grooves and are particularly useful in dynamic applications due to a lower rate of friction and wear.
| Flange SealsPolyurethane AU 93A -40/220F [-40/104C] 3000 PSI [207 Bar] |  |  | 
OV flange seals are mostly used to seal threaded tube connections and fittings. As torque is applied to the connector, the elastomeric seal material is compressed to form a positive sealing line, and its special geometry keeps it from twisting during installation.
| NBR 70A -40/225F [-30/100C] FPM 75A -15/400F [-26/205C] EPDM -65/450F [-54/232C] Silicone -70/300F [-57/149C] |  |  | 
Metric O'Ring cord is supplied as a continuously extruded profile. O'Ring cord can be used to manufacture custom O'Rings when no standard size is available. A wide variety of cross-sections and sizes are available.
| Back-up RingsV.PTFE -320/450F [-196/232C] |   |  | 
Back-up rings are auxiliary devices used in conjunction with standard seals such as O'Rings and U-Cup type seals. SD/T rings are manufactured out of PTFE material, supplied either in solid or in split versions.
| Back-up RingsPolyurethane -40/195F [-40/91C] |  | 
Same as SD/T Back-up rings but in 90 durometer polyurethane material.

Usit Rings are metal washers with a trapezoidal elastomeric element bonded to their inside diameter. Used primarily with threaded fasteners and flanged or hydraulic connectors. they are positively actuated via the torque applied to the hardware assembly
