MRbrew 4" Keg Tap Manual Party Pump for American D‑System Kegs — Chrome, Spring‑Loaded Seal

MRbrew 4" Keg Tap is a manual party pump that fits American D‑system kegs and dispenses draft beer without CO2 or regulators.

Simple, rugged and portable, this chrome‑plated hand pump converts standard 5‑gallon North American party kegs into a gravity/piston‑served tap system. It uses a spring‑assisted sealing washer and a piston handle to build and hold pressure so beer flows on demand. No external gas, no complex setup — just insert, seal, pump and pour.

How does the MRbrew pump create pressure without CO2?

The pump relies on a piston and a lubricated spring washer to compress air inside the keg headspace. Repeated strokes pressurize the keg; the built‑in clamp and seal minimize leakage so that pressure stays steady for multiple pours.

• Spring‑loaded washer for consistent sealing and smooth operation
• Piston rod handle builds air pressure manually—no cylinders needed
• Hose clamp and barbed fittings reduce hose leaks at the connection

Will this work with my keg—what fits the American D system?

This MRbrew model is sized for the common 4" American D‑system party kegs used by major domestic brands. It slips into the D fitting and forms a seal suitable for branded 5‑gallon kegs and many party keg styles.

• Compatible with common US domestic party kegs (Bud, Miller, Coors, etc.)
• Designed for the 4" American D top fitting standard
• Simple removal and reinstallation for reuse or deposit return

How durable and easy to maintain is the hand pump?

MRbrew built this pump with chrome plating and robust hardware so it resists rust and cleans easily after use. The removable hose and piston allow routine lubrication and simple replacement of wear parts, extending service life for repeated events.

• Chrome‑plated exterior for corrosion resistance and easy cleaning
• Sturdy piston and rod construction for long‑term use
• Serviceable components—clean, lube or swap washers and hoses

How do I use the keg pump at a party or picnic?

Set your keg in an ice chest, secure the pump into the D fitting, tighten the hose clamp, then operate the piston handle until beer flows. Keep the keg chilled and re‑pump as needed during service; no power source is required.

• Place keg in ice, seat pump into the top fitting, tighten connection
• Pump handle several times to build dispensing pressure
• Pour, then top up pressure with additional strokes as needed

Who is this for? The MRbrew 4" Keg Tap is ideal for hosts, tailgaters, caterers and outdoor entertainers who want a portable, easy‑to‑operate draft solution without CO2 equipment. It suits anyone who uses American D‑system party kegs and wants a reusable, heavy‑duty pump to serve cold beer at weddings, picnics, game‑day events and backyard gatherings.
