Description
Overview:
The Piston Bumper for Hikoki/Hitachi nailers is a genuine OEM service part (OEM No. 886289) that cushions the piston at the end of its stroke to absorb impact and reduce shock loads inside the tool. Made from a durable moulded elastomer, it helps prevent damage to the driver, cylinder and cap, while maintaining smooth cycling and consistent driving power. Designed specifically for selected Hikoki finish nailers, it offers a precise fit and reliable sealing within the nose/cylinder area. Ideal for routine maintenance or repair, it restores correct clearances when the original bumper becomes worn or cracked through regular use. Suitable for models such as the GBNT1665 and NT65GA, it supports dependable performance on site or in the workshop.
Key Features:
- Genuine Hikoki/Hitachi OEM part for assured compatibility and fit
- Direct replacement for OEM No. 886289 with no modifications required
- Durable elastomer construction to withstand repeated high‐impact cycles
- Helps protect piston, driver and cylinder components from premature wear
- Maintains smooth operation and consistent driving performance
- Supports reliable tool startup and return stroke behaviour
- Easy to fit during routine strip-down with basic hand tools
- Suitable for professional site work and regular maintenance schedules
- Stable fit for both Hikoki and legacy Hitachi-branded equivalents
- Cost-effective preventative replacement to reduce downtime and repair costs
Typical Applications:
Used during servicing of finish nailers employed in second fix carpentry, trim and architrave fitting, skirting, door casings, shopfitting, joinery and light framing tasks. Replacing a worn bumper helps maintain driving consistency in hardwoods, softwoods and MDF, supporting clean nail setting and reducing recoil for users in trade, maintenance, and hire fleet environments.
