Parback® backup ring with a curved cross-section.

Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.

90A Durometer | Buna-N Rubber Material | 2 7/8 in Nominal Inner Diameter | 1/8 in Cross Section | Backup Ring

Features

• Excellent extrusion resistance
• Easily stretched for installation
• Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces

Solid Urethane backup ring with a flat cross-section.

95A Durometer | Urethane Material | 3 1/8 in Nominal Inner Diameter | 3/16 in Cross Section | Backup Ring

Features

Solid Urethane backup ring with a flat cross-section.

95A Durometer | Urethane Material | 5 3/4 in Nominal Inner Diameter | 1/4 in Cross Section | Backup Ring

Features

• High strength and abrasion resistance
• Wide temperature range
• Chemical resistance
• Low friction
• Easy installation

Wear rings provide a hard-wearing surface that protects the cylinder walls and the piston rod from scoring and abrasion. By maintaining alignment and reducing side loads, these rings facilitate smoother piston movement and lower friction levels.

Nylon Material | 2 in Nominal Inner Diameter | 1/8 in Cross Section | Wear Ring

Features

• Protection Against Wear
• Reduced Friction
• Extended Cylinder Life
• Operational Efficiency

The Hallite 533 is capable of withstanding high side loads and preventing metal-to-metal contact between the piston and the bore or the rod and the gland.

The PA 533 material is heat stabilised 33% glass reinforced nylon 66, which offers excellent bearing properties.

Compatible with hydraulic and lubricating oils. The PA 533 material is not recommended for use in water based fluids (HFA) or where significant water is present, due to the swell of the nylon.

DUCT-11000 has a diameter of 11 in. The material is 65-45-12 Ductile Iron.

65-45-12 Ductile Iron is used to machine pistons, glands, caps, manifolds, rams, and valve bodies.

Ductile has higher machining speeds than steel and there is usually no need for deburring machined parts. The graphite flakes in the material act as a self-lubricant. Ductile can be flame or induction hardened as well as deep hardened.

Ductile bars are produced with sufficient stock on the outside diameter to ensure clean-up at the nominal dimension.

• Excellent machinability
• Optimal impact strengths
• Optimal fatigue properties
• Optimal electrical conductivity
• High magnetic permeability

Full mill lengths will be cut to lengths between 12 ft and 19 ft long. Packages longer than 44 inches may have additional freight charges.

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 | 6 in Nominal Inner Diameter | Buffer Seal

This capped piston seal consists of a filled PTFE cap, a T-shaped NBR energizer, and two split nylon backup rings. It exhibits low friction, high sealability, and excellent resistance to extrusion and wear.

PTFE Material | 65 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

This wiper is molded from high grade urethane and bonded to a carbon steel case in a single lip design.
