TIME-SERT® Spark Plug Thread Repair Kit – M14 x 1.25 Short Washer Seat (10-Piece Set)

TIME-SERT® M14 x 1.25 Short Spark Plug Thread Repair Kit – Washer Seat Version – 10 Piece Set

The TIME-SERT® M14 x 1.25 Short Spark Plug Thread Repair Kit is specifically designed to permanently repair damaged or stripped spark plug threads in cylinder heads where a short insert length is required. Supplied with 16.8mm solid steel inserts, this washer seat version restores original thread integrity while maintaining correct spark plug positioning and sealing.

Unlike temporary thread repair methods, TIME-SERT® uses a solid bushing insert that locks permanently into the parent material, creating a strong, reliable repair suitable for high-temperature and high-vibration engine environments.

Key Benefits

• Extended 16.8mm Insert Length – Ideal for applications requiring deeper thread engagement and additional holding strength.
• Permanent Spark Plug Thread Repair – Restores damaged threads without the need for oversized spark plugs or temporary repair solutions.
• Solid Steel Insert Technology – Provides a stronger and more durable repair compared to traditional wire-type inserts.
• Heat & Pressure Resistant – Suitable for demanding engine environments where reliability is critical.
• OEM-Quality Repair – Trusted by professional workshops, engine builders, and technicians worldwide.

Why Choose TIME-SERT®?

TIME-SERT® thread repair systems are recognised worldwide as one of the most effective methods for restoring damaged threads. The patented installation process expands and locks the lower portion of the insert into the base material, creating a secure mechanical bond without the need for adhesives.

Furthermore, the flanged insert design ensures precise positioning and prevents the insert from winding down into the hole during installation. As a result, repairs remain secure even after repeated spark plug removal and installation.
