Dongguan Walle Sealing Technology Development Co., Ltd.
Four-lobed seals,four-lobed rings, quad seals, X rings, four lip seals
QUAD-RINGRSeal is used predominantly for dynamic sealing functions. Its use is always limited by the pressure to be sealed and the velocity.
Standard materials for QUAD-RINGR:
NBR 70  -306 to 100Standard 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
In contrast to the O-Ring, QUAD-RINGRSeal 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-RINGRSeal cross-section, a high sealing effect is achieved. - A lubricant reservoir formed between the sealing lips improves start up.
- Unlike anO-Ring, themould line flash lies in the trough, between and away from the critical sealing lips.
