what size is the injector thread on an esprit injector?

[Glass Doctors UK]

Does anyone know the diameter and pitch of this as it would also be the same as the novus one too i would assume. probably imperial.

Does anyone know if the Novus plastic injectors work with any other brand of bridge? I have a big bag full of Novus injectors.

Yes they fit in many other makes of equipment, I cannot tell you the thread size, bit to technical for me.

[screenman]

Could that thread size be 1/2 inch unf.

Most of the sizes that manufacturers use are 1/2 X 20. That is 1/2 inch by 20 threads per inch. Some are different, LR and maybe a few others but most are this size.

so if you were going to buy a drill and tap for the injector it would be
1/2" UNF ?
1/2" UNC ?
1/2" BSP ?
...
Starstruck, if we knew what country you were in from your profile someone might see your post and offer to buy them from you

He is in the USA, I would use 1/2 unf. I do not use Novus style injectors now due to the fact I prefer Delta, but there are plenty of good copies out there that are inexpensive.

I am from the USA and I wasn't really wanting to sell them. I was just interested in finding out which other bridges work well with novus injectors?

[Nomad]

Sorry, been away from the computer for a while. Here in the US it is, I believe, called 1/2 national fine thread. National course would be 1/2 X 13 threads per inch.

LRI has several bridge options that fit the 1/2" novus type injectors including the new MVP360 bridge.
