Molded from filled PTFE and machined to close tolerances, these seals feature low friction and excellent wear characteristics. Nitrile rings are used for energizers.

70A Durometer | PTFE Material | 64.5 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded in PTFE with a rubber energizer, this seal absorbs the shock of pressure spikes to protect the rod seal. Bronze-filled Teflon rod buffer seal with a rubber energizer.

Bronze Filled PTFE Material | 2 in Nominal Inner Diameter | Buffer Seal

Utilizing a sturdy metal case, these wipers are molded from the same high performance urethane used in our Heavy Duty U-seals. Built for severe service, these wipers are capable of surviving hostile environments.

92A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter

Features

• Used in Heavy Duty U-seals

Molded in PTFE with a rubber energizer, this seal absorbs the shock of pressure spikes to protect the rod seal.

70A Durometer | Filled PTFE Buffer Material | 80 MM Nominal Inner Diameter | Buffer Seal

2-1/2 Bronze Rod Glands

These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible. Piston diameter “I” dimensions are given for pistons without wear rings.

40% Bronze Filled PTFE Material | 3.884 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Molded in bronze-filled PTFE with an FKM energizer, this seal is used to protect the primary seal from damage caused by pressure spikes and excessive heat build up.

Bronze PTFE Buffer Material | 80 MM Nominal Inner Diameter | Buffer Seal

Molded from 93 Shore A polyurethane with a 70 Shore A energizer, this seal utilizes the same groove dimensions as a standard o-ring or T-seal. One or two Style 575 back-up rings may be used for wider grooves. Extrusion resistant by design, this seal is also resistant to rolling and twisting. Installation is an easy two step snap-in procedure with no need to re-size before insertion into the bore. Piston diameter “I” dimensions are given for pistons without wear rings.
