Four-lobed seals, four-lobed rings, quad seals, X rings, four lip seals
QUAD-RINGRSeal is used predominantly for dynamic sealing functions. It’s use is always limited by the pressure to be sealed and the velocity.
Standard materials for QUAD-RINGR:
NBR 70 -30℃6 to 100℃Standard material for hydraulics and , pneumatics. Mineral , oil-based hydraulic
fluids, animal and , vegetable oils and , fats, aliphatic , hydrocarbons, silicone oils and, greases, water up to +80°C
Viton 70 -18°C to +200°C Mineral oils and , greases, flame , retardant liquids, aliphatic, aromatic , and chlorinated , hydrocarbons, petrol, 99 octane , petrol, diesel fuels, silicone oils and , greases
Advantages
In contrast to the O-Ring, QUAD-RINGR Seal has the following advantages:
- Avoids twisting in the groove. Due to its special profile, the seal does not tend to roll in the groove during reciprocating movement.
- Low friction.
- Very good sealing efficiency. Due to an improved pressure profile over QUAD-RINGR Seal cross-section, a high sealing effect is achieved. - A lubricant reservoir formed between the sealing lips improves start up.
- Unlike an O-Ring, the mould line flash lies in the trough, between and away from the critical sealing lips.
