Brass pigtail, nickel plated, with ntl seal and rubber cap

• 5mm (M5) thread ( pitch is 0.8 mm ) to 4 mm hose tail

• Can be permanently installed on motorcycles that only have a screw plug in the vacuum port

• Eliminates the need to install adaptors before every carburetor synchronisation,  just pull off the caps and push on the gauge hose.

If you are making your own Manometer, these will serve as your connectors

• Rubber caps are included to seal vacuum

• Sold individually, sale includes 1 x adaptors. 1 x rubber seal, 1 x rubber push on covers

Don't over tighten, its brass and they just need to "pinch up"

Pictures show installation and use on  Honda VT700 ( Shadow), I recommend carrying the original blanking plugs in your tool kit in case a cover gets lost( they don't need a fixing as its vacuum rather than positive pressure)

Will send Royal Mail within UK
