Maddog 36in Stainless Steel Fill Whip Hose Extension - Fast Re-Fills

In this review of the Maddog 36in Stainless Steel HPA Fill Whip Hose Extension the bottom line is simple: it is for players and hobbyists who want a durable, long-reach charging line to refill HPA or PCP tanks without removing them from a pack. The single biggest reason to buy is the 36in heavy duty stainless steel construction and 4500 psi rating that let users work at a refill station with more freedom of movement and confidence that the hose will stand up to repeated use.

Key Features

• 36in stainless steel hose: The length and heavy-duty braid provide reach and abrasion resistance so you can keep a tank mounted while refilling.
• 4500 psi rated assembly: Built to handle high-pressure compressed air systems used in paintball, airsoft and PCP airguns for safe refills.
• 1/8in quick disconnect ends: Male and female quick-connect fittings make attaching and detaching the whip fast and straightforward at a fill station.
• Works with HPA and PCP tanks: Compatible with common compressed air tanks and compressor setups, making it a versatile charging accessory.
• Sealed fittings: All fittings are securely sealed to reduce the chance of leaks and maintain reliable performance when used correctly.

Who It's For

The Maddog fill whip is aimed at paintball players, airsoft enthusiasts, and PCP airgun owners who regularly refill tanks and want the convenience of a 3ft extension to avoid removing tanks from packs or rigs. Users who value rugged construction and industry-standard quick-disconnect fittings will appreciate how it streamlines repeated charging tasks.

It is not intended for CO2 systems or for uses outside paintball/airgun charging as directed, so people running CO2 tanks or those seeking a multi-gas charging line should look elsewhere. Also, buyers who require custom fittings beyond 1/8in quick-disconnects may need adapters not included with the whip.
