TS-199-3020 is a Turbosmart LockSleeve 90 degree turbo compressor outlet adapter machined from billet aluminum for a 2.50 inch outlet on both ends. Designed exclusively for Turbosmart B Frame and C Frame turbocharger compressor covers, this adapter uses the Plazmaclamp / Plazmaman Clamp connection type (sold separately) to deliver a weld-free, boost-rated seal rated to 150 PSI. As a Race Only component, it is intended for closed-course competition use and is not legal for use on pollution-controlled vehicles in California or elsewhere where emissions regulations apply.
LockSleeve Technology
The LockSleeve system replaces conventional welded compressor outlet adapters with a precision-machined screw-together ferrule assembly. Two billet aluminum collar halves thread together around the compressor outlet, compressing an internal O-ring against the outlet flange to form a mechanically interlocked, pressure-rated seal.
Because the connection is fully mechanical, no heat is introduced to the turbocharger housing during installation. There is no risk of warping the compressor cover, no specialist welding equipment required, and the assembly can be disassembled and reinstalled without damaging the seal. The internal O-ring is captive within the ferrule halves, keeping it correctly positioned as the collar is tightened.
The result is a boost-rated seal that meets or exceeds the performance of a welded adapter, at a fraction of the installation time, while remaining fully serviceable in the field.
Compatibility

Frequently Asked Questions
What turbos are compatible with TS-199-3020?
This adapter is compatible with Turbosmart B Frame and C Frame turbocharger compressor covers only. It is not compatible with Precision Turbo, Garrett, or Borg Warner turbochargers. Always confirm your turbo frame designation before ordering.
Does the Turbosmart LockSleeve require welding?
No. The LockSleeve system is entirely weld-free. The two precision-machined billet aluminum collar halves thread together around the compressor outlet, and the internal O-ring creates the boost-rated seal mechanically. No heat, no welder, and no specialist fabrication skills are required.
Is the Plazmaclamp included with this adapter?
No. The Plazmaclamp / Plazmaman Clamp is sold separately and is not included with this adapter. Only the LockSleeve ferrule assembly (two collar halves with internal O-ring) is included in the box.
What is the maximum boost pressure this adapter can handle?
The LockSleeve ferrule assembly is rated to a maximum of 150 PSI. This exceeds the boost levels of virtually all street and competition applications.
Can I use this adapter on a Garrett or Precision Turbo?
No. This product is engineered specifically for Turbosmart B Frame and C Frame compressor cover geometries. It will not fit or seal correctly on Garrett, Precision Turbo, or Borg Warner housings.
Is this product legal for street use in California?
No. This is a Race Only product with no CARB EO number. It is not legal for use on pollution-controlled vehicles on public roads in California or in other jurisdictions with similar emissions regulations. It is intended for closed-course competition use only.
What is the outlet size on both ends of this adapter?
Both the inlet and outlet ends measure 2.50 inches. The 90 degree elbow maintains the same 2.50 inch diameter throughout.
What is the difference between the 3019 and 3020 variants?
Both the TS-199-3019 and TS-199-3020 are 90 degree, 2.50 inch LockSleeve adapters for Turbosmart B Frame and C Frame turbos. The only difference is the connection type: the 3019 uses a Vibrant HD Clamp interface, while the 3020 uses a Plazmaclamp / Plazmaman Clamp interface. Choose based on the clamp system used in your charge pipe build.
Can the LockSleeve be removed and reinstalled without replacing the O-ring?
Yes. Because the ferrule halves thread together mechanically and the O-ring is captive within the assembly, the adapter can be disassembled and reinstalled without damaging the seal under normal service conditions. Inspect the O-ring for wear or damage any time the assembly is disassembled.
Where is the Turbosmart LockSleeve made?
The LockSleeve is precision-machined from billet aluminum in Australia.
What warranty does this product carry?
Turbosmart provides a 1-Year Limited Warranty covering defects in materials and workmanship under regular use and correct installation. The warranty applies to purchases from authorized dealers only and runs from the original date of purchase.
