What This Seal Helps Address

• Sealing loss caused by a flattened or hardened O-ring
• Leaks after turbo oil line service or removal
• Contamination around the turbo oil feed or return sealing point
• Fitment issues when replacing an OE-style turbo oil line seal

Installation Notes and Tips

Inspect the sealing groove and mating surfaces before installation. Replace the seal if it shows cuts, flattening, swelling, or heat damage, and verify the dimensions match the original application before assembly. Clean oil residue from the connection area so the O-ring seats evenly.
