Turbosmart TURTS-199-3023 Turbo Adapter 2.5in 90 Elbow Hose Barb

TS-199-3023 is a 90-degree turbo compressor outlet adapter from the Turbosmart LockSleeve series. Precision-machined from billet aluminum, this 2.50 inch hose barb adapter fits Turbosmart B Frame and C Frame turbocharger compressor covers only. It delivers a weld-free, mechanically interlocked boost-rated connection rated to 150 PSI. Intended for closed-course competition use only. Race Only not legal for California pollution-controlled vehicles. A coupler is sold separately and is not included with this part.

LockSleeve Technology

The Turbosmart LockSleeve system replaces traditional welded turbo outlet connections with a screw-together ferrule assembly. Two precision-machined billet aluminum collar halves thread together around the compressor outlet, compressing an internal O-ring to form a boost-rated, leak-free seal. No heat, no welding, and no risk of heat distortion to your compressor cover or charge pipe. The result is a mechanically interlocked connection that holds rated boost pressure without the permanence or complexity of a weld.

The ferrule design distributes clamping load evenly around the full circumference of the outlet, preventing the localized stress points that can develop with traditional clamp-only setups. The internal O-ring provides a positive pressure seal independent of the outer clamping force, giving the system a secondary line of defense against boost leaks under sustained competition loads.

Introduced at SEMA 2025, LockSleeve represents Turbosmart's answer to teams that need a reliable, serviceable, and repeatable outlet connection without welding infrastructure in the pits or shop.

Compatibility

This adapter is designed for Turbosmart B Frame and C Frame turbocharger compressor covers only. It is not compatible with Precision Turbo, Garrett, or Borg Warner turbochargers. Do not attempt to fit this adapter to non-Turbosmart compressor covers.

The 90-degree elbow configuration routes the 2.50 inch outlet perpendicular to the compressor face, making it useful in tight engine bays where a straight outlet would conflict with other components. Both inlet and outlet ends measure 2.50 inches for a consistent bore through the adapter.

Clamp not included. A compatible clamp must be sourced separately. For silicone hose or coupler setups, a standard T-bolt or HD clamp of the correct diameter is recommended. Hose or coupler is also sold separately.

What's Included

• 1x LockSleeve ferrule assembly (two precision-machined billet aluminum collar halves with internal O-ring)

Hose, coupler, and clamp are sold separately and are not included.

Full Specifications

LockSleeve Series Variants

The Turbosmart LockSleeve line covers multiple outlet configurations for Turbosmart B Frame and C Frame compressor covers. All variants share the same billet aluminum ferrule technology and 150 PSI pressure rating.

The straight configuration (TS-199-3029) is priced lower than the 90-degree versions. If your charge routing permits a straight outlet, the TURTS-199-3029 offers the same LockSleeve ferrule seal at a reduced cost.

Frequently Asked Questions

What turbos are compatible with the Turbosmart LockSleeve TS-199-3023?

This adapter is compatible with Turbosmart B Frame and C Frame turbocharger compressor covers only. It will not fit Garrett, Precision Turbo, or Borg Warner turbochargers. Always verify your turbo frame designation before ordering.

Do I need to weld anything to install the LockSleeve adapter?

No welding is required. The LockSleeve system uses a screw-together ferrule assembly with an internal O-ring to create a mechanically interlocked, boost-rated seal. The two collar halves thread together around the compressor outlet without any heat or welding equipment.

Is a clamp or coupler included with this adapter?

No. This adapter includes only the LockSleeve ferrule assembly (two collar halves with internal O-ring). A compatible hose, silicone coupler, and clamp must be sourced and purchased separately.

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 operating pressures of virtually all street and competition forced induction applications using B Frame and C Frame Turbosmart units.

Can I use this adapter on a Garrett or Precision turbocharger?

No. This adapter is machined specifically to the compressor outlet dimensions of Turbosmart B Frame and C Frame turbochargers. It is not compatible with Garrett, Precision Turbo, or Borg Warner compressor covers and should not be used on those platforms.

Is this adapter legal for street use in California?

No. This is a Race Only product with no CARB Executive Order number. It is not legal for use on California pollution-controlled vehicles and is intended solely for closed-course competition use sanctioned by a recognized racing organization.

What is the outlet diameter on both ends of this adapter?

Both the inlet and outlet ends measure 2.50 inches. The 90-degree elbow routes the charge path perpendicular to the compressor cover face while maintaining a consistent 2.50 inch bore throughout.

What is the difference between this 90-degree adapter and the straight LockSleeve variant?

This straight variant (TS-199-3029) uses a Vibrant HD Clamp connection (sold separately). Both share the same 2.50 inch outlet diameter, billet aluminum construction, and LockSleeve ferrule seal technology. The straight version is priced lower than the 90-degree versions.

Where is the Turbosmart LockSleeve manufactured?

The LockSleeve adapter is manufactured in Australia using precision-machined billet aluminum.

What warranty does the LockSleeve carry?

Turbosmart provides a 1-Year Limited Warranty from the date of purchase when bought through an authorized dealer. Coverage applies to defects in material and workmanship under regular use and correct installation. The warranty does not cover damage from improper installation, misuse, or use outside the product's specified application.
