Rubber Material | 1 3/4 in Nominal Inner Diameter | Wiper

Rubber Material | 1 3/4 in Nominal Inner Diameter | Wiper

Molded in urethane, this wiper features a double lip which prevents fluid that seeps by the rod seal from exiting the cylinder.

Urethane Material | 25 MM Inner Diameter | Wiper

The Style PSC is a double acting piston seal designed to replace o-rings, quad-rings, and T-seals with the same groove dimensions (O-ring dash number). Style 575 urethane back-up rings may be added to either or both sides of the “PSC” to accommodate wider groove widths. The PSC is made of 95A Durometer polyurethane, giving it high extrusion and abrasion resistance. The crowned sealing surface produces a positive seal from vacuum to high pressure. Hercules® Sealing Products also offers a wide base (WB) Style PSC piston seal. These wide base seals have the same characteristics of the standard PSC seals but offer a wider base, eliminating the need to use back-up rings to accommodate wider grooves. Piston diameter “I” dimensions are given for piston without wear rings.

95A; 70A Durometer | Polyurethane Material | 3 1/8 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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 | 56.4 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.

95A; 70A Durometer | Polyurethane Material | 3 5/8 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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 | 6.16 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Suffix “V” designates fluorocarbon material,“N” designates nitrile material, and “HT” designates high temperature urethane.

5 in induction hardened chrome shafting.

The base material is 1045/1050 Carbon Steel with 0.0005 in (0.0127mm minimum)-thick chrome plating and a case depth of 0.05 in (1.27 mm).

Induction Hardened Chrome is typically used in abrasive envrionments where the cylinder is exposed to rocks or heavy debris. Also used to machine clevis pins.

• Greater strength
• Better resistance to mechanical damage

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.
