Air Hold Fitting Set - GearWrench

Specifications

The GearWrench Air Hold Fitting Set, model 901, is a compact and lightweight tool, weighing 0.2 lbs. This set includes 14mm and 18mm adapters, which are threaded for 1/4" NPT (National Pipe Thread) connections.

Key Features

• Dual-Size Adapters: Comes with 14mm and 18mm adapters for compatibility with common spark plug thread sizes.
• Compressed Air Connection: Adapters are threaded for 1/4" NPT to securely connect to standard air hoses.
• Direct Cylinder Access: Designed to screw directly into the spark plug port of an engine.
• Valve Retention: Utilizes compressed air to keep engine valves closed and held firmly in place.

Applications

This Air Hold Fitting Set is specifically designed for automotive service and engine maintenance. It is primarily used to apply air pressure to the cylinder, enabling technicians to perform valve service without the need to remove the cylinder head. Typical applications include:

• Replacing valve springs.
• Servicing or replacing valve stem seals.
• General valve train maintenance requiring valve retention.
• Can be used with various valve spring compressors (e.g., GearWrench 912, 915, 2078, 3087, 3271).

Benefits

• Prevents Valve Drop: Securely holds valves in the closed position, mitigating the risk of them falling into the cylinder during servicing.
• Increases Efficiency: Allows for quicker valve spring and valve stem seal replacement by eliminating the need for cylinder head removal.
• Time-Saving: Streamlines engine repair procedures, reducing overall service time.
• Reduces Labor: Simplifies complex valve train maintenance tasks, potentially reducing labor efforts.
