Frequently asked questions

What is the O-Ring (AEU1628) used for?
The O-ring seals a connection in the air conditioning refrigerant circuit. It's fitted at hose unions and component joints, including the evaporator and blower motor connections, to give a refrigerant-tight seal and stop the system losing its charge.
How many O-rings do I need for an air conditioning repair?
You'll typically need one O-ring for each joint you open. When servicing the AC system it's usual to renew every O-ring on any union that's disturbed, so order one per connection rather than reusing the old seals.
Can the air conditioning O-ring be reused?
AC O-rings are typically single-use. Once a refrigerant joint has been opened the seal can take a set, so fitting a fresh O-ring is the usual practice to keep the connection refrigerant-tight and avoid a slow leak.
Which Land Rovers does this O-ring fit?
This O-ring fits the air conditioning system on the Land Rover Defender (1987-2006), Discovery 1 (1989-1998) and Range Rover Classic. Use your VIN to confirm the AC layout on your vehicle. Alternative code STC3171 is also listed.
