LockNLube BTX Battery Transfer Pump Stem Kit - 5 gal (20 L)

Fast, Clean Fluid Transfer, Anywhere!

Add a dedicated 5 gal (20 L) stem to your existing BTX System.

The LockNLube BTX 5 gal (20 L) Stem Kit lets you expand your BTX System by dedicating a stem to a specific fluid or container. Designed for mechanics, fleet technicians, and shop owners already running the BTX Power Head, the Stem Kit eliminates the need to clean between fluid changes — just move the Power Head to the appropriate stem and go.

The BTX Stem stays with the container, keeping your fluids separate and your workflow clean. Each stem uses sealed wetted parts and a built-in drain-back valve to prevent cross-contamination, spills, or drips when switching between jobs. The same BTX Power Head drives every stem, so one motor handles your entire fluid inventory.

The 5 gal (20 L) Stem Kit is ideal for shops and service trucks running multiple pails of different fluids. This kit includes the Stem Assembly, Reinforced Hose, and Dispensing Gun — everything needed to add a clean, dedicated fluid line to your existing BTX setup.

BTX Power Head, Battery, and Charger sold separately (see BTX Starter Kit).

Suitable Fluids

Engine oil, gear oil, hydraulic oil (up to SAE 140), ATF, and engine coolant.
