HK Army Elite Thread Protector and Fill Nipple Kit

The HK Army Elite Thread Protector & Fill Nipple Kit is a must-have upgrade for protecting your HPA tank from accidental damage during transport, play, or storage. The CNC-machined thread protector shields your tank’s regulator threads from dings, drops, and cross-threading, while the included fill nipple cover prevents dirt, paint, and moisture from entering your fill port—one of the most common causes of leaks and regulator issues. Lightweight, durable, and built for reliability, this kit keeps your HPA tank performing at its best while adding a clean, professional look to your setup.
