About This Product
If you work on excavators or construction gear, these hydraulic test couplers are total lifesavers.

This 5-piece kit gives you M12x1.
5 threaded adapters that hook right into your pressure testing gear.

Made from carbon steel with a galvanized finish, they handle temps from -40 to +100°C without breaking a sweat.

The tubular design means easy hookup to measuring instruments, and the metal protective cover stays put – no loosening, no pressure loss.
Sealing is top-notch too; they connect even under system pressure, and the steel ball keeps everything tight until you're ready.

No leaks, no drama.

Compact and lightweight, so you can toss 'em in your tool bag without hassle.

Perfect for hydraulic systems, pressure checks, exhaust work, or oil sampling.

Reliable, practical, and built to last.
