This dual end stainless steel dental pick is ideal for extracting O-rings, and backup rings from hydraulic cylinders without damaging cylinder bores. The Indigo™ 22575 hydraulic seal removal dental pick is an essential tool for hydraulic equipment repair.
Hydraulic equipment operators and maintenance technicians understand that seal failure in cylinders, pumps, and valves leads to costly downtime and environmental concerns from fluid leaks. However, removing old O-rings, backup rings, and buffer seals from precision-machined cylinder bores and glands presents a significant challenge: one scratch in the bore can create a permanent leak path, requiring expensive cylinder replacement or re-honing.
The specialized Indigo™ 22575 O-ring and gasket removal dental pick features dual-geometry tips designed for hydraulic seal extraction. The curved tip hooks under rod seals, piston seals, and O-rings in cylinder glands, while the angled tip reaches backup rings and buffer seals in recessed grooves. The 410-grade stainless steel construction provides the rigidity needed to extract hardened seals compressed by thousands of PSI, while the polished finish reduces the risk of scoring cylinder walls compared to rough-finished picks.
The tool's textured grip ensures secure handling even when working with hydraulic fluid contamination, and the autoclavable stainless steel resists corrosion from hydraulic oils and cleaning solvents used during cylinder rebuilds.
Indigo™ dental tools are made with AISI 410 German surgical grade stainless steel, not "alloy steel" made from rusted cars. We've been selling dental tools on-line since 1998. Ours stay sharp longer & are autoclavable: see Documentation below that confirms chromium & manganese content.

When used at proper angles, the risk is minimal. The 410-grade stainless steel has a polished finish that reduces friction, and the curved tip geometry distributes contact force. However, always work carefully, hydraulic cylinder bores are precision-ground, and any scratch can create a leak path. Use the hook action to extract seals rather than scraping along bore walls.
Yes. Hydraulic seals often become extremely hard after years under high pressure. The stainless steel construction provides the rigidity needed to work under these compressed seals without the tip bending. For severely stuck seals, apply penetrating oil and allow it to soak before attempting removal.
Backup rings sit in recessed grooves and require the angled tip for access. Insert the tip at a shallow angle between the backup ring and groove wall, then work around the circumference. O-rings are typically easier and can be removed with the curved hook tip.
Exercise caution. While the tool is less aggressive than improvised alternatives, chrome plating can be scratched. Work at very shallow angles and avoid dragging the tip along the chrome surface. Focus on hooking under rod seals rather than scraping across the plating.
Yes. The tool works on hydraulic systems across all applications—construction equipment, agricultural machinery, industrial presses, and mobile hydraulics. Seal designs are similar regardless of equipment type, though sizes may vary.
