SPOOLOGIC Turbo to Spyder O-Ring

The SPOOLOGIC SL-310-003 Turbo-to-Spyder O-Ring replaces the compressor outlet seal on Late 1999–2003 Ford 7.3L Powerstroke Super Duty trucks and 2000–2003 Excursions. This black Viton O-ring seals the connection between the turbocharger outlet and intake spider, helping prevent boost leaks at the joint. Also called a turbo outlet O-ring or compressor discharge seal, it fits the late-style GTP38 connection and compatible GTP38R turbochargers that retain that outlet design.

Turbo Outlet Sealing

This O-ring sits in the compressor discharge groove and seals against the mating spider connection. It helps contain pressurized air as it leaves the turbocharger and enters the charge-air plumbing.

Age, damage, or incorrect positioning can prevent the seal from seating properly. Inspect it whenever the spider assembly is disconnected or the turbocharger is replaced. A fresh O-ring restores the sealing element at this joint; damaged flanges, misalignment, and clamp problems must be addressed separately.
