Rocklin Hydraulics Gannon Seal Kit 6-Pk for 1-1/8″ Rod, 3″ Bore

Description

Product Overview

The Rocklin Hydraulics Gannon Seal Kit is engineered to meet the rigorous demands of modern hydraulic systems used in agricultural and construction equipment. Each kit contains six precision‑machined seals crafted from a proprietary nitrile‑urethane blend that balances flexibility with exceptional wear resistance. This material choice enables the seals to maintain their integrity under high pressure, temperature fluctuations, and abrasive contaminants commonly encountered in field operations. The kit is specifically sized for rods measuring 1‑1/8″ in diameter and barrel bores of 3″, making it a direct replacement for original equipment manufacturer (OEM) parts on a wide range of machinery.

Key specifications include a maximum operating pressure of 5,000 psi, a weight of just 1.06 ounces per seal, and compliance with industry standards for hydraulic cylinder accessories. The compact packaging dimensions of 5.55 × 4.49 × 1.18 inches ensure easy storage and handling, while the included six‑piece set provides all the components needed for a complete seal replacement without the need for additional purchases. Designed for both single‑acting and double‑acting cylinders, the seals deliver consistent performance whether the hydraulic system is extending or retracting the piston rod.

Compatibility is a cornerstone of the Gannon Seal Kit’s design. The kit aligns with Rocklin’s catalog numbers such as 13‑503, 13‑5xx, and other models that share the 1‑1/8″ rod and 3″ bore configuration. This broad compatibility reduces inventory complexity for service technicians and ensures that the same high‑quality seal solution can be applied across multiple equipment platforms, including box scrapers, mower decks, tractor implements, and cutting blades. By standardizing on this seal kit, operators benefit from reduced part variation, streamlined maintenance procedures, and improved overall equipment reliability.

Usage

In practical terms, the Gannon Seal Kit excels in environments where hydraulic cylinders are subjected to frequent cycling and heavy loads. For example, box scrapers used in earthmoving applications rely on robust seals to prevent fluid leakage that could compromise digging efficiency and increase wear on the cylinder walls. The nitrile‑urethane composition of the seals provides a self‑lubricating surface that minimizes friction, thereby extending the service interval and reducing the need for frequent oil top‑ups.

Similarly, mower decks and tractor implements benefit from the kit’s high pressure rating, which ensures that the hydraulic actuation of cutting blades remains smooth and responsive even under demanding conditions such as thick vegetation or uneven terrain. The seals’ resistance to oil degradation and temperature extremes means that they maintain their sealing capability throughout the entire operating season, delivering consistent performance from the first day of use to the last. By installing the Gannon Seal Kit, operators can expect lower downtime, fewer unexpected repairs, and a noticeable improvement in the overall efficiency of their hydraulic systems.

FAQ

What types of hydraulic cylinders are compatible with this seal kit?

The Gannon Seal Kit is compatible with any hydraulic cylinder that uses a 1‑1/8″ diameter rod and a 3″ bore size. This includes many models of box scrapers, mower decks, tractor implements, and cutting blade assemblies. Always verify the specific part numbers in your equipment manual to confirm compatibility.

Can the seals be used in both single‑acting and double‑acting cylinders?

Yes, the seals are engineered to function effectively in both single‑acting and double‑acting hydraulic cylinders. Their flexible nitrile‑urethane material accommodates the dynamic motion of the piston rod while maintaining a tight seal under pressure, regardless of the cylinder’s operating mode.

How does the nitrile‑urethane material improve seal performance?

Nitrile‑urethane combines the oil‑resistance of nitrile rubber with the elasticity of urethane, resulting in a seal that resists swelling, abrasion, and temperature extremes. This blend provides a self‑lubricating surface that reduces friction, extends service intervals, and helps prevent premature wear in harsh operating environments.

What is the recommended installation procedure?

Begin by depressurizing the hydraulic system and removing the old seals. Clean the cylinder bore and rod thoroughly to eliminate debris. Install the new seals using the supplied installation tool, ensuring they are seated evenly without twisting. Re‑pressurize the system and check for leaks before returning the equipment to service.

Does the kit include any tools or accessories?

The kit includes six seals but does not contain installation tools or additional accessories. Rocklin Hydraulics offers a range of compatible installation tools and kits that can be purchased separately to facilitate a smooth and efficient seal replacement process.
