M12 x 1.25mm to M18 x 1.5mm adapter kit

This pack contains three straight male connectors that join an M12 x 1.25mm thread to an M18 x 1.5mm thread. The fittings are built from corrosion-resistant material rated for high temperature and high pressure without leakage. They suit pneumatic, fuel or water lines in automotive and workshop plumbing. Each piece is a full-port straight adapter for direct in-line connection.

Mechanics and DIYers matching these exact threads

Technicians who need to bridge M12 x 1.25mm and M18 x 1.5mm ports on air, fuel or coolant circuits will find the correct thread match here. Installers requiring a different thread pitch, a female port, an elbow shape or a quick-disconnect mechanism will not be served by this kit. Buyers working with metric threads outside the stated 1.25mm and 1.5mm pitches must source alternative adapters.

Thread specification M12 x 1.25mm to M18 x 1.5mm

The sole decisive figure is the thread pairing: one end cuts an M12 x 1.25mm male thread, the other an M18 x 1.5mm male thread. If the equipment you are joining does not present exactly those two thread forms, the adapters will not seal. No other dimension or feature in the listing alters this compatibility requirement.

Questions about this item

Will the M12 x 1.25mm thread match the existing port on my older compressor?

The adapter has an M12 x 1.25mm male thread on one end; verify your compressor port uses the same pitch before fitting.

How can I confirm the M18 x 1.5mm seal is holding pressure after installation?

Pressurise the line and apply soapy water to the joint; no bubbles indicate a leak-free connection at the M18 x 1.5mm end.

Does the pack include sealing washers or thread tape for the M12 and M18 threads?

The box contains only the three straight adapters; washers or PTFE tape must be purchased separately.
