Description
Overview:
The Piston O-Ring for Hitachi / Hikoki NV50A1 and NV50AA coil nailers is a genuine replacement part designed to restore and maintain reliable air sealing inside the piston assembly. Manufactured from a durable synthetic rubber elastomer, it helps prevent air leaks and keeps driving pressure consistent, which supports accurate and repeatable nail driving. As an OEM component (part no. 876174), it offers the correct fit and compatibility for selected Hitachi and Hikoki pneumatic nailers, reducing the risk of premature wear or performance loss. This Genuine Part is suitable for routine servicing or repair work where the original O-ring has hardened, flattened or been damaged, helping extend the working life of the tool and minimise downtime on site or in the workshop.
Key Features:
- Genuine Hitachi/Hikoki OEM part (876174) for assured compatibility and fit
- Durable elastomer construction resists compression set and wear in pneumatic use
- Maintains a tight air seal to prevent leaks and preserve consistent driving power
- Helps reduce misfires and loss of performance caused by worn seals
- Supports tool longevity by protecting the piston and cylinder from bypassing air
- Easy to install during standard maintenance with basic hand tools
- Cost-effective fix for weak drive, double firing, or irregular nail depth
- Suitable for professional, trade, and DIY maintenance schedules
Typical Applications:
Used during servicing and repair of Hitachi/Hikoki coil nailers to correct air leaks and restore reliable operation. Ideal for tools used in roofing, fencing, cladding, pallet and crate assembly, and general construction where consistent drive depth and fast cycling are required.
