Nitrogen Fill Valve

M5 Valve – Nitrogen Charging Valve for WP & Non-Serviceable Shocks

The M5 Valve is a high-quality solution for nitrogen charging on WP shocks and other suspension systems. It works especially well on shocks without a dedicated nitrogen port or those marked as non-serviceable. By replacing the factory reservoir bleed screw, it creates a secure and reusable nitrogen charging port compatible with standard nitrogen needles.

This valve is built for serious suspension work. The CNC-machined brass body offers superior corrosion resistance and clean thread engagement. Additionally, it holds up to the rigors of repeated nitrogen fills. A high quality O-ring and precision sealing washer ensure a reliable, leak-free seal every time.

Features:

• Precision CNC-machined brass construction — more resistant to galling and wear than common plated steel alternatives
• Reusable design — suitable for both small batch or regular workshop use
• Compatible with WP piggyback shocks and other shocks without a nitrogen port
• Includes sealing O-ring and washer — ensures proper sealing under pressure
• Compact and professional appearance — flush-fit design integrates cleanly with the reservoir

Applications:

• WP piggyback shocks (KTM, Husqvarna, GasGas)
• Shocks without a nitrogen port or labeled as non-serviceable
• Ideal for both professional shops and DIY suspension tuners
