Introduction

K616 is a rod seals. It prevents leakage in medium pressure efficiently in hydraulic purpose. It is our universal multi-lip packing that is highly regarded for its long working life and ability to operate under adverse mechanical conditions. When used in split form it can provide major downtime savings.

They are an extremely seal making installation very easily. K616 profile was designed  to provide improved  sealing performance and stability in the gland. A knife trimming process  is used  to form the. By design, the K616 is an economic choice. It is designed to ensure a tight static side seal when installed.

The sealing lips are accurately machine trimmed to ensure good low pressure sealing while the material

resists extrusion at high pressures.

Features

Ø  Excellent wear & abrasion resistance.

Ø  Easy installation.

Ø  Long life

Ø  Low compression

Ø  Shock load  resistance and increase seal performance at zero pressure.

Ø  Additional sealing edge, prevents ingress of dirt to a large degree.

Ø  Recommended for safety critical applications and for adverse mechanical conditions.

Ø  Double-acting capabilities when fitted back-to-back.

Ø  Excellent resistance to extrusion and wear.

Ø  Options available to suit adjustable and non-adjustable axial length housings.

Ø  Available with Self-aligning Gland Ring.

Application

Ø  Hydraulic application

Ø  Cranes

Ø  Steel mill

Suitable for use with most mineral-based hydraulic fluids at temperatures up to 100°C (212°F). Also resistant to air and most lubricating oils and greases. Where fire-resistant fluids of the water/oil emulsion or water/glycol types are used, please contact our Technical Support Team for advice on temperature limits
