Effortlessly Connect Two Ball Lock Liquid QDs Without Tubing

The Simplest Way to Transfer, Purge, or Sanitize Between Kegs

The Ball Lock Jumper is a stainless steel, double-ended ball lock post designed to directly connect two liquid ball lock quick disconnects (QDs). This compact, no-tubing solution is perfect for any homebrewer looking to simplify keg-to-keg transfers, purge oxygen from receiving kegs, or run cleaner or sanitizer through a closed loop system.

Whether you're transferring beer under pressure, purging a serving keg with CO2, or pushing sanitizer through your lines, this jumper allows you to do it cleanly and efficiently without needing extra hoses or fittings. Its low-profile design makes setup fast and foolproof—just click two liquid disconnects in place and you're ready to go.

Key Features:

  • Material: Made from 100% stainless steel for maximum durability and corrosion resistance
  • Design: Double-ended liquid ball lock post for connecting two liquid QDs directly
  • Includes: Two pre-installed post O-rings for a secure, leak-free seal
  • Compatibility: Fits standard ball lock liquid quick disconnects (black QDs)

Common Uses:

  • Keg-to-Keg Transfers: Easily transfer beer or sanitizer between kegs without opening them or exposing contents to air
  • CO2 Purging: Purge oxygen from a clean keg using pressure from a filled keg—ideal for oxygen-sensitive beers
  • Closed-Loop Cleaning: Recirculate PBW or sanitizer through your keg lines without disassembling your system

Why Use a Ball Lock Jumper?

  • No Tubing Required: Cleaner, faster setup—just click and go
  • Minimizes Oxygen Exposure: Great for IPAs and other beers that are sensitive to oxidation
  • Compact and Reusable: Small enough to store in your kegging kit and built to last

Pro Tip:

Pair this jumper with a pressurized keg of CO2 or sanitizer to fill or clean another keg completely closed and under pressure. It's a must-have for serious keggers looking to reduce oxygen pickup and streamline transfers.
