TecMate TS-400 CarbMate and SynchroMate Premium ROTAX Aircraft Engine Crossover Tube Synchronizer Adapter Kit

The TecMate TS-400 is a specialized, professional-grade diagnostic accessory designed explicitly to adapt CarbMate (TS-110) or SynchroMate tuning instruments to ROTAX dual-carburetor light aircraft engines. Synchronizing carburetors on a ROTAX engine requires splitting the intake balance/crossover compensating tube, which leaves an uneven setup of one open male elbow and one open female hose line. The TS-400 resolves this challenge entirely with a custom-engineered adapter framework that securely taps into both sides of the split line, allowing for highly accurate electronic balancing without causing vacuum leaks or damaging fragile intake components.

Features and Benefits

• Official ROTAX engine optimization — Specifically engineered for aviation mechanics and DIY pilots looking to safely and precisely synchronize the twin carburetors on ROTAX light-aircraft powerplants.

• Seamless tool integration — Acts as the factory-approved direct link for the TecMate CarbMate and SynchroMate electronic throttle valve and carburetor synchronizers.

• Perfect crossover tube bridging — Uniquely matches the geometry of the split manifold balancing line, attaching directly to the intake manifold's male elbow on one cylinder and the crossover tube’s female hose on the other.

• Precision-engineered 11 mm diameter — Features a heavy-walled 11 mm inside diameter (ID) framework to achieve a perfect, airtight friction seal against factory ROTAX fittings.

• Eliminates false vacuum leaks — Guarantees a fully sealed connection loop during active testing, preventing unmetered air from leaning out the cylinders and causing false gauge readings.

• Generous 6-foot routing length — The 180 cm (6 ft) lines provide a long, safe buffer distance, letting you position your delicate testing electronics completely clear of hot cylinder heads, manual throttle linkages, or aircraft propeller arcs.

• Fuel- and oil-resistant construction — Built with premium, commercial-grade rubber compound hoses designed to resist softening, swelling, or cracking when exposed to aviation fuel (Avgas/Mogas) and engine oils.
