Hytrel backup ring with a flat cross-section.
Molded of 55D Durometer Hytrel, these back-up rings provide excellent extrusion resistance and tolerance to fluids such as phosphate esters, hydraulic oil and water. Stretched for installation, they return quickly to their original size for easy installation.
55D Durometer | Hytrel Material | 6 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | Backup Ring
Features
- Improved extrusion resistance compared to standard FKM or NBR backups
- Can be stretched over larger diameters and will return quickly to their original size
- High strength and abrasion resistance
- Wide temperature range
- Chemical resistance
- Low friction
- Easy installation
Style 580 Square O-rings are circular elastomeric rings that create a seal between two or more parts. They are made from a variety of materials, including BUNA-N rubber, and are used in a variety of industries, including automotive, aerospace, and manufacturing.
Buna-N Rubber Material | 5 1/4 in Nominal Inner Diameter | 1/4 in Cross Section | Square O-ring
Features
- Pressure range varies according to diametral clearance
- Temperature range of -40 °F to -240 °F
O-rings as elastic loops that seal static and dynamic applications. They are used to seal the space between cylinders, pistons, pipes and tubes and can be made from various materials.
70 Durometer | Buna-N Rubber Material | 3/8 in Nominal Inner Diameter | 1/16 in Cross Section | O-Ring
Features
- Pressure range varies according to diametral clearance
- Temperature range of -40 °F to -240 °F
Molded in urethane, this wiper is flexible enough to easily snap into a groove yet tough enough to handle difficult rod wiping applications.

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.

HC-5625-12 has a 6.5 in OD and is made to fit a 5 in bore cylinder.
Head cap size is determined based on the bending stress.
A static seal or o-ring is used in between the head cap and barrel (except welded construction).
The main function of the head cap is to enclose the pressure chamber at one end. The cap is connected to the cylinder body by means of welding, threading, bolts, or tie rod.
HT-5500X4750 has a wall thickness of 0.375 in. The ID is 4.75 in and the OD is 5.5 in. The material is DOM 1026 Carbon Steel and has been stress-relieved and annealed.
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.
