Frequently asked questions

What is the LR031797 air conditioning O-ring used for?
The LR031797 O-ring seals a joint in the air conditioning system, sealing refrigerant connections against leaks. It fits the Discovery 4 (2010-2016) and Range Rover Sport L320 (2010-2013). These rings keep the A/C circuit pressure-tight at pipe and component unions.
How many A/C O-rings are typically needed for a repair?
Typically you'll need one O-ring per connection being opened, but A/C repairs usually disturb several joints, so many workshops replace all the seals in the area at once. Ordering a few is common practice to avoid reopening the system for a single leaking ring.
Should the A/C O-ring be replaced whenever a connection is opened?
Yes, these A/C sealing rings are typically single-use. Once a refrigerant joint on the Discovery 4 or Range Rover Sport L320 is separated, fitting a fresh O-ring is standard practice for a leak-free seal. Reusing an old ring often leads to slow refrigerant loss.
