Kastar 73103 Compression Tester Adapter 14mm Female to 12mm Male

The Kastar 73103 is a precision-engineered compression tester adapter designed for accurate engine diagnostics on small displacement engines. This solid brass adapter converts a 14mm female connection to a 12mm male connection, allowing you to use compression testers with 14mm fittings on engines with 12mm spark plug ports.

Key Features:

• 14mm female (M14-1.25) to 12mm male (M12-1.00) thread configuration
• Constructed from solid brass with black oxide finish for corrosion resistance and durability
• Precision threading ensures secure, leak-free connections during compression testing
• Compatible with CLT-2 compression testers and most standard compression testing equipment
• Ideal for snowmobiles, motorcycles, outboard motors, and other small engines

This adapter is an essential tool for mechanics and technicians who need to perform compression tests on a variety of engine types. The brass construction provides excellent durability while maintaining the precise tolerances required for accurate compression readings. The black oxide finish protects against corrosion and extends the working life of the adapter.
