Turbosmart TS-199-3030 Turbo Adapter 2.5in Straight Plazmaclamp

TS-199-3030 is a straight (0-degree) 2.50-inch turbo compressor outlet adapter from the Turbosmart LockSleeve series, engineered specifically for Turbosmart B Frame and C Frame turbocharger compressor covers. Using the Plazmaclamp (Plazmaman clamp) connection type and rated to 150 PSI, this billet aluminum ferrule assembly delivers a weld-free, boost-rated seal through a precision-machined screw-together collar system. Intended for closed-course competition use only. This is a Race Only product and is not legal for use on pollution-controlled vehicles in California.

LockSleeve Technology: How the Ferrule System Works

The Turbosmart LockSleeve system replaces traditional welded or clamped silicone couplers with a precision-machined billet aluminum ferrule assembly. Two collar halves thread together around the compressor outlet and the intercooler or charge pipe, compressing an internal O-ring to form a mechanically interlocked, boost-rated seal. The result is a connection that resists blow-off under sustained boost pressure up to 150 PSI without any welding, heat, or permanent modification to the compressor cover.

Because the ferrule threads together under mechanical load rather than relying on clamp friction alone, the LockSleeve design maintains sealing integrity even under repeated thermal cycling and high-vibration racing environments. The billet aluminum construction keeps weight low while providing the rigidity needed to hold a consistent O-ring preload across the full pressure range.

Compatibility

This adapter is designed to fit Turbosmart B Frame and C Frame turbocharger compressor covers only with a 2.50-inch compressor outlet. It is not compatible with Garrett, Precision Turbo, or Borg Warner turbochargers.

Full Specifications

LockSleeve Series: Sibling Variants

The Turbosmart LockSleeve lineup covers multiple outlet diameters and angles to match different compressor cover configurations. This straight 2.50-inch variant sits at the lower end of the price range. Other sizes and angles in the series include:

• 2.50-inch, 90-degree elbow versions for installations where the charge pipe exits at a right angle to the compressor cover
• 3.00-inch variants (such as the 90-degree TS-199-3037) for Turbosmart B Frame and C Frame turbos with a 3.00-inch compressor outlet

The straight 2.50-inch configuration (this SKU) is priced lower than the 90-degree elbow variants. If your compressor outlet is 3.00 inches, see the 3.00-inch LockSleeve models. If your charge pipe routing requires a 90-degree turn directly off the turbo, see the 90-degree 2.50-inch variant. All LockSleeve models share the same core ferrule technology and 150 PSI pressure rating.

Frequently Asked Questions

What turbos is TS-199-3030 compatible with?
This adapter fits Turbosmart B Frame and C Frame turbochargers with a 2.50-inch compressor outlet. It is not compatible with Garrett, Precision Turbo, or Borg Warner turbochargers.

Does the Turbosmart LockSleeve 2.50-inch straight adapter work without welding?
Yes. The LockSleeve system uses a screw-together billet aluminum ferrule with an internal O-ring to create a boost-rated, mechanically interlocked seal. No welding is required.

What clamp does the 2.50-inch LockSleeve straight adapter use?
This model uses a Plazmaclamp (also called a Plazmaman clamp). The clamp is sold separately and is not included in the box.

How much boost pressure can the Turbosmart LockSleeve handle?
The LockSleeve series is rated to a maximum of 150 PSI.

Can I use the LockSleeve 2.50-inch straight adapter on the street?
No. This is a Race Only product with no CARB EO number. It is intended for closed-course competition use only and is not legal for use on pollution-controlled vehicles operated on public roads, including in California.

What is the difference between the straight and 90-degree LockSleeve 2.50-inch versions?
The straight (0-degree) version connects the compressor outlet to a charge pipe running in a straight line. The 90-degree elbow version routes the charge pipe at a right angle directly off the turbo. The straight variant is priced lower than the 90-degree versions.

What is the difference between the 2.50-inch and 3.00-inch LockSleeve models?
The 2.50-inch models fit Turbosmart B Frame and C Frame turbos with a 2.50-inch compressor outlet. The 3.00-inch models, such as the TS-199-3037 90-degree elbow, fit the same turbo families but with a 3.00-inch compressor outlet. Always match the adapter outlet size to your compressor cover outlet diameter.

Is the LockSleeve 2.50-inch straight adapter made from cast or billet aluminum?
Billet aluminum only. Both collar halves of the ferrule assembly are precision-machined from billet aluminum, not cast. This ensures tight dimensional tolerances for consistent O-ring sealing.

Where is the Turbosmart LockSleeve made?
The Turbosmart LockSleeve series, including this 2.50-inch straight adapter, is made in Australia.

What warranty does the Turbosmart LockSleeve carry?
Turbosmart provides a 1-Year Limited Warranty covering defects in material and workmanship under regular use and correct installation, purchased through an authorized dealer.
