Hi Folks,

I wanted to replace my injectors and chanbers and I'm not sure I have the correct items. Chamber is 5S6795 and the injector body is 8S2389. judging from the photo unless the nut is special I don't see how the injector fits in the screw chamber. Any advice would be welcome.

Hi,

this pic may help show how these capsule nozzle injectors are fitted--torque for the capsule nozzle nut is 100 lb/ft.

Only tighten the nozzle to the body finger tight--the torque applied to the retaining nut causes the seal between these components, the nozzle opening pressure is around 600psi so a leak here is unlikely unless debris or rust pits etc. are on said faces.

Cheers,

Eddie B.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
