Single-lipped, snap-in rod wiper is designed to fit D-style housings.
The ST-XLF wipers are designed to fit the standard ST wiper groove. These wipers include a dust lip to prevent contaminates from entering through the groove. They also have a ribbed inside diameter for low friction operation and to prevent pressure traps between the wiper and rod seal. Developed specifically for use in harsher environments with heavy contamination, such as in agriculture, off-highway, and forestry equipment.
Urethane Material | 4 in Nominal Inner Diameter
Features
- Precision trimmed wiping lip
- Retrofits most ‘D’ wiper housings
- Especially effective in vertically mounted cylinders
- Designed to follow the rod deflection caused by side loads
- Interchangeable with Hallite 520 wiper
- Sharp wiping lip scrapes heavy contamination from rod protecting sealing system
- Umbrella Wiper Technology™ protects housing from contamination and reduces moisture ingress
Style ST wiper rings are precision molded from 90A durometer urethane. Flexible enough to easily snap into a groove yet tough enough to handle difficult rod wiping applications. “V” tagged wipers are constructed of fluorocarbon.

SB44ES has a 1.75 in ID.
The bushing is Unsealed and made of forged steel. The ball will swivel like a fish eye with 3-5 degrees of movement.
Style ST-XL wipers are molded from premium urethane and are direct replacements for Style “ST” or “D” wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminates from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.

- Ribbed ID to prevent pressure traps
Featuring high pressure and high shock load capability, this seal utilizes the same twin lip design found in Hercules®, Sealing Products’ RTU style. With the main body of the seal molded from high performance polyurethane, this seal, incorporates a dynamically designed nitrile energizer and a tough polyacetal anti-extrusion ring. RTUB is capable of, pressures up to 10,000 psi in approved applications. Please consult Hercules Engineering for pressures above 6,000, psi.
The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The unique profile of the NBR energizer ensures the primary sealing lips maintain contact under low or no pressure situations while ensuring proper sealing at higher pressures. The Hallite 621 also incorporates an acetyl anti-extrusion ring to withstand side loads and extreme pressure peaks even with the extrusion gaps.

T-Seals combine a resilient sealing ring with a hard, split back-up ring on each side of the sealing element. The assembly installs in a standard o-ring groove. T-Seals are non-spiraling and extrusion resistant to 5,000 psi with improved tolerances. Intermediate and Wide Base T-Seals are designed to fit MIL-5514F o-ring glands only and interchange with 1 o-ring / 1 back-up ring and 1 o-ring / 2 back-up ring grooves, respectively.
