Product Description
DDMA piston seal-TDMA hole sealed-TDMA-TDMA combined sealing piston seal
1. Standard material
Seal: PTFE F-PTFE
Elastomer: NBR NBR or polyurethane PU
2. Applications
DDMA for a variety of liquid applications tandem seal, an internal seal. Mainly for the piston and plunger seal. In mineral oil, modified mineral oil, flame retardant hydraulic oils and the use of compressed air.
TDMA lips mouth by an elastic body, consisting of a combination seal wear ring. Before installation, the sealing lip protruding cylinder pressed after installation, provides elasticity towear rings, even in the case of no pressure to achieve good sealing effect. Detachablesealing ring on both sides of the liquid, but also to the oil chamber of the seal, and other fluids to prevent intrusion.
Design and apply reference Hunger's TDMA series standards.
 
3. Features and Benefits
1. Low friction, no stick-slip phenomenon.
2. High wear resistance.
3. Easy to install, good sealing effect, the pressure and harsh conditions with very high pressure stability.

The Hunger TDMA tandem seal for multi-fluid outside sealing application is used to seal pistons and plungers.

It can be used with mineral oils and in modified form with compressed air.
The TDMA seal consists of two parts, an elastic ring of PUR with 2 sealing lips and a slide ring of abrasion-resistant PTFE-Bronze Compound with 2 sealing edges. Prior to fitting, the sealing lips protrude beyond the nominal diameter of the seal, and are pressed against the cylinder wall after fitting. Thus effective sealing is provided even at zero pressure.

The slide ring is surrounded by the elastomer sealing ring and moves axially in direct contact with the inside of the tube. With increasing pressure and compression of the elastic ring, it is the slide ring which is predominantly pressed against the inside of the tube. The outer sealing surface of the TDMA mainly comprises the slide ring which has excellent sliding properties.
