Stop oil leaks – thanks to M15 x 1.5 thread taps
The M15 x 1.5 tap cuts away damaged material and reforms the thread profile so a new plug can seat correctly. High-speed steel construction keeps the cutting edge stable during repeated passes.
Restored threads accept a tight-fitting plug that seals reliably, reducing drips and the need for more invasive repairs.
Ready-to-fit replacements – with six oil drain plugs and aluminium washers
Six matching drain plugs accompany the tap, and aluminium washers compress to form a crush seal between plug and pan. Multiple plugs mean several repair opportunities without sourcing parts mid-job.
Immediate replacements keep a repair session moving and allow for repeat fixes across several vehicles or further future maintenance.
Versatile underbody repairs – with suitability for sump, gearbox and differential threads
The M15 thread specification in the kit matches common drain plug sizes for both sump and gearbox/differential applications listed by the manufacturer. The tap is sized to rethread shallow to medium damage where the pan itself remains serviceable.
A single kit covers several common leak points under a vehicle, making workshop and roadside repairs more efficient.
