The Metabo HPT Air Refill Valve (part 384002M) is a maintenance accessory for Metabo HPT 18V Cordless Pneumatic nailers. This is an air refill valve kit designed for refilling the air in the nailer's sealed air spring drive during routine service. The kit includes the air refill valve and a hex wrench for installation.

Metabo HPT's Cordless Pneumatic nailers drive nails with a charge of compressed air sealed inside the tool rather than a hose. The air refill valve gives you a way to top up that charge as part of normal maintenance, so the nailer keeps the drive power it was designed for.

Metabo HPT built the Cordless Pneumatic family around on-site service. Paired with the Maintenance Jig Kit (384003M) and the Wearable Parts Kit for your model (384005M for the strip nailers, 384015M for the NV1890DA coil nailer), this valve lets a crew handle routine maintenance on the jobsite instead of shipping the tool out.

Any crew running more than one Metabo HPT Cordless Pneumatic nailer should keep one of these in the truck.

• Why it stands out: It is the official Metabo HPT valve with the install wrench included.
• Worth knowing: Follow the nailer's owner's manual for the refill procedure and pressure, and you will still need an air source to refill.
