Alde Gas Leak Detector Fluid Refill – Bubble Leak Test Fluid for LPG

The Alde Gas Leak Detector Fluid is a genuine replacement refill fluid for Alde bubble-type gas leak detectors used on caravan, motorhome, marine and LPG-powered systems. It contains propylene glycol formulated for clear bubble formation when gas escapes under pressure — helping you visually detect potential leaks at joints, connections and appliances.

This small sachet is intended to top up or replace the fluid in an Alde leak tester (e.g., Alde 4071 bubble tester), keeping the leak indicator working accurately. Ideally the fluid is replaced if it becomes milky or contaminated, or if it’s been in use for several years.

Why Choose This Leak Detector Fluid?

• 🔍 Clear Bubble Leak Detection – Formulates sharp, visible bubbles when gas leaks occur into the tester chamber.

• 🛡 Maintains Safety Checks – Keeps your Alde gas leak tester working properly for ongoing gas safety inspections.

• 🔄 Easy to Refill – Simply open the tester sight glass, add fluid to mark and replace glass for use.

• 🏕 Caravan & LPG Use – Suitable for propane and butane systems in caravans and motorhomes.

• 🔋 Affordable & Essential Part – Small refill sachet for routine maintenance without needing a full new tester.
