Description
The Lennox 49J23 Teflon O-Ring 12Pack is a set of replacement rings which are used to form a seal to prevent leakage in several HVAC appliances. These O-rings, usually produced from rubber or Teflon as this pack, are vital parts that are placed between two faces to stop leakage. They are flexible in a way that they can be compressed to form a compact mass with a tight surface. In HVAC systems, O-rings are used in compressors, pumps and valves and other applications that involve pressure changes.
