Product Description
Seal-TDI TDI shaped coaxial rod seals combination of ring-TDI

1. Seal-TDI TDI shaped coaxial rod seals combination of ring-TDI
2. Standard material
Sealing the body: F-PTFE PTFE
Y-shaped ring: NBR NBR or polyurethane PU
3. Applications
TDI consists of a shaft with a ladder shaped ring and a shaped elastomer composition,ladder ring forms a complex with dual piston rod surface sealing effect. Shaped elastomersealing effect and provide elastic shaft ladder ring for wear from the compensation. Suitable for hydraulic cylinder piston rod seal, generally used in conjunction with the guide sleeve.
Design and apply reference Hunger's TDI series standards.
4. Features and Benefits
1. Low friction, no stick-slip phenomenon
2. High wear
3. Under pressure and harsh conditions with very high pressure stability, good sealing effect.
 The Hunger TDI tandem seal for inside sealing is a piston rod seal.
It can be used with mineral oils and in modifi ed form with water base fl uids, fi re resistant fl uids and compressed air.

The TDI seal consists of 2 parts, an external elastic ring of PUR with a sealing lip and an internal slide ring of abrasion resistant PTFE-Bronze compound with a sealing edge. Prior to fi tting, the sealing lip protrudes beyond the nominal diameter of the seal and when fi tted is pressed against the piston rod. Effective sealing is thereby provided at zero pressure.

The slide ring is surrounded by the elastic ring and seals axially in direct contact with the piston rod. Under increasing pressure and compression of the sealing ring, it is the slide ring which is predominantly pressed against the piston rod. The slide ring produces an annular cavity where any seepage oil that has passed the elastomer lip is collected.
