When a hydraulic cylinder starts leaking or loses pressure, a cross-compatible seal kit is often the most cost-effective fix. This guide focuses on cross hydraulic cylinder seal kits that fit standard 2″ to 3″ bore sizes used in agricultural and industrial equipment. Ideal buyers include fleet managers, shop technicians, and serious DIY enthusiasts who want factory-grade performance without replacing the whole cylinder. Below you’ll find five top options, a side-by-side quick comparison, and practical buying tips.

Cross Repair Seal Kit for 3″ Bore x 16″ Stroke Cylinder
Best for customers repairing a Cross 316DB cylinder. This kit focuses on restoring sealing surfaces with a steel, durable seal set designed for long service life. Best for technicians who want a direct replacement without machining or custom parts.
Who it’s for: shop technicians and fleet maintenance teams replacing worn seals on Cross cylinders. Why selected: direct compatibility with 3″ bore Cross cylinders improves leverage against oil leaks and reduces cylinder downtime. Caution: verify bore and stroke match before ordering to avoid misfit seals.
Replacement Skid Steer Lift Hydraulic Cylinder Seal Kit
Best for Bobcat equipment models listed in the compatibility notes. This kit targets 2″ bore hydraulic cylinders with a 1-1/4″ rod diameter, making it suitable for common skid steer replacements. It’s a practical choice when OEM parts are preferred but full cylinder replacement isn’t necessary.
Who it’s for: owners or technicians maintaining older Bobcat machines. Why selected: broad model compatibility helps reduce guesswork. Caution: confirm the OEM part numbers 6803329 or 7137769 to ensure proper matching, as bore and rod specs vary across Bobcat units.
All States Hydraulic Cylinder Seal Kit 3″ Bore
Best for standard 3″ bore hydraulic systems with a 1-1/4″ rod. This kit provides essential seals for a straightforward overhaul, and its specifications—bore and rod details—help buyers confirm fit before purchase.
Who it’s for: operators needing a reliable, straightforward 3″ bore kit. Why selected: predictable sizing aids quick, accurate installation. Caution: verify your rod diameter as listed than rely on bore size alone to prevent seating issues.
PU Hydraulic Oil Seal Kit – 5PCS
Best for industrial and agricultural equipment overhaul requiring robust polyurethane seals. The 5-piece set includes piston seals, rod wipers, U-cups, and O-rings, all designed for oil resistance and abrasion durability. Best for heavy-duty environments where wear resistance matters.
Who it’s for: shops needing a complete repair kit with durable materials. Why selected: polyurethane offers extended service life under demanding conditions. Caution: check if your system requires Viton or fluorocarbon seals for higher temperature or chemical exposure.
3 Pack Hydraulic Seal Installation Tools
Best for installers seeking safer, faster seal seating. This set covers three rod-diameter ranges and includes a kidney-bean bending action to reduce seal damage during installation. Useful for those who frequently overhaul cylinders and want to minimize fitting errors.
Who it’s for: technicians and experienced DIYers who value ease of use. Why selected: installation aids reduce mistakes and speed up repairs. Caution: ensure the tool sizes match the rod diameters in your project, as mismatched tools can cause seal damage during seating.
5 Pack Hydraulic Seal Installation Tools
Best for complete seal installation kits that include multiple sizes. These tools provide quick seating and a secure grip to minimize slippage while seating U-cups and rod seals. Ideal for shops handling a range of cylinder sizes.
Who it’s for: workshop teams that perform regular cylinder maintenance. Why selected: multi-size versatility supports varied repair jobs. Caution: review each size range to ensure compatibility with your seal groove dimensions.
Buying Guide: Key Purchase Considerations
What size is your cylinder and what type of seals does it require? Start by confirming bore, rod diameter, and stroke, then match to the kit’s included seals. Cross-compatible kits often suit multiple brands, but exact dimensions matter for proper seating.
Material and durability: polyurethane seals offer strong wear resistance and oil compatibility, while steel and other composites may be preferred for high-pressure or harsh environments. Consider temperature exposure and chemical compatibility when selecting seals.
Installation ease: seal installation tools reduce the risk of damage during seating. Look for sets with multiple sizes and ergonomic handles for comfortable use during longer repair sessions.
Compatibility notes: some kits are optimized for Bobcat, Cross, or All States cylinders. Always cross-check OEM part numbers and cylinder bore size to avoid misfits that could lead to leaks or performance issues.
Cost vs. downtime: while a complete kit may seem more expensive, it can save downtime by enabling a full overhaul in one service event, rather than returning for additional parts later.
