🔌 Function

⚠️ Common Signs of Failure

• Weeping or dripping from the joint the ring seals
• Ring gone hard, squared off or taken a permanent set
• Cracking or splitting on the ring surface
• Nipped or trapped ring, showing a witness mark where it was pinched on assembly

• Check whether your engine carries an air compressor before ordering - that is the whole distinction on this row
