HK Paintball Airsoft Fill Whip Hose Extension 4500 Psi - 36in

In this review we tested the HK Paintball Airsoft Fill Whip Hose Extension to see if it makes tank refilling faster and more reliable for field use. The bottom line: this 36in braided stainless hose is built to handle up to 4500 psi, and it is best for players and techs who need a durable, flexible link between a compressor or tank and a refill station. The review focuses on fit, build quality, and how well the included quick-disconnect adapter and gaskets perform during repeated fills.

Key Features

• High pressure stainless steel: The braided stainless steel construction supports up to 4500 psi for safe use with high-pressure PCP and refill stations.
• 36in length: A 36in hose gives room to maneuver and positions the fill station away from the user for easier access during filling.
• Universal quick-disconnect ends: The 8mm quick-release male plug and female socket on each end make it straightforward to connect to many common fill valves and regulators.
• Included double male nipple: The package includes an 8mm quick disconnect double male fill nipple so users can adapt the hose to existing gear without searching for extra fittings.
• Durable gaskets: Two replacement gaskets are included so you can reseal connections after repeated use to reduce small leaks over time.

Who It's For

This hose is aimed at paintball and airsoft players, range techs, and field support personnel who refill compressed air tanks and need a robust, long-lasting charging whip. Its stainless braid and high pressure rating suit owners of PCP rifles and refill stations that routinely work near the 3000 to 4500 psi range.

People who should look elsewhere include casual users who only fill with low-pressure setups or those who need an integrated regulator or pressure gauge built into the whip. If you require a custom length or a different quick-disconnect size, consider hoses made for that specific configuration.

Pros & Cons

Pros

• Strong braided stainless construction that resists kinking and looks finished with plated polish.
• Comes with a double male quick-disconnect nipple so getting started is simple and fast.
• 36in length gives flexibility and better reach when refilling without changing tank positions.
• Includes spare gaskets to help maintain seal integrity after repeated connections.

Cons

• Some customers report variable leak performance; careful gasket seating is necessary to avoid leaks.
• Not a substitute for a hose with an integrated regulator or gauge if you need those features built in.
