- GOK type 4071 leak tester with 90° outlet for LPG systems in motorhomes and caravans. Press the button and a leak shows as bubbles in the sight glass. Connections RST 8 x RVS 8, max. 2 bar, pressure loss below 1 mbar.
The GOK type 4071 is a leak tester installed permanently in the LPG system of a motorhome or caravan. Press the button and any leak in the system after the tester shows up as bubbles in the sight glass. This version has a 90° outlet: an 8 mm pipe socket (RST 8) on the inlet side and an 8 mm compression fitting (RVS 8) with coupling nut type M and olive type D-MS on the outlet side. The housing is marked Alde Leak Detector 4071.
How it works
- quick leak check of the whole system after the tester at the press of a button
- a leak shows as bubbles in the sight glass
- the glycol mixture supplied allows testing also below 0°C
- maximum working pressure 2 bar, pressure loss below 1 mbar
- test as often as needed - the manufacturer recommends every time the gas system is used and at every cylinder change
Where to install it
- suitable for all low pressure LPG systems in motorhomes and caravans; it can also be retrofitted
- as close as possible to the regulator outlet, ideally in the gas cylinder locker; otherwise in a place protected from UV light and water
- always before any gas fittings or appliances
- vertically with the sight glass clearly visible, following the flow direction arrows - gas must not pass in the opposite direction
- fit supporting sleeves on copper tubes; sleeves and fixing screws are included
How to test
- open the main valve on the gas cylinder
- switch off all gas appliances and wait about 60 seconds until the flame failure devices cut off the gas (a click can be heard)
- press and hold the red button at the bottom for at least 10 seconds, longer in large systems
- wait at least one minute for the first bubble; if the following bubbles come more than 10 seconds apart, the system can be deemed sound
- if the tester shows a leak, do not use the system; find the leak with soapy water or a leak detection spray
Topping up and checking the tester
- close the cylinder valve, unscrew the sight glass and fill to the top mark, then refit the sight glass and check the gasket
- after filling, do not turn the tester upside down as the liquid may run out
- after topping up, check the tester itself for leaks - a leak in the tester also produces bubbles
- check the liquid level regularly
- function check: run an appliance with low gas consumption (e.g. the fridge) and press the button fully - bubbles mean the tester works
