RAW Rapid Sekhmet gauge for HM1000x - Dimensional issue!

[Geneeus]

Not at all! This revised product has just become available, and a lot of us with RAW rifles have had an issue where the nipple is too long, and as a result, cannot be installed far enough to allow the o-ring to compress sufficiently to seal. And if I only commented on things I was sure of, I wouldn't have anything to say! <grin>

And you are 100% correct about the dowty seal, and the teflon tape. Lots of folks don't know the difference between the two types of threads.

Dowty washers wont seal the gauge on the RAW, because the quick-fill v-block has an o-ring pocket cut into it. A dowty washer is too big to fit into that pocket, so it will leak. You must use a washer on the RAW gauges. Don’t use teflon tape, because they aren’t 1/8 NPT tapered pipe thread, they are 1/8 BSPP straight thread.

I'm getting ready to replace my gauge with one from HUMA and I would also like to replace this o-ring. Does anyone know what size it is?

Thanks!

Hey Guys,
Just installed the Sekhmet Pro in one of my RAW HM1000x … using the OEM gauges O-ring.
It leaks, hopefully I have a new spare O-ring which will seal?

The OEM gauge was screwed very tight in the V block.

Bummer! Hopefully you have a spare. If the spare works, can you please post the size? I need to replace my RAW gauges too.

Thanks!

Had an old service kit from Martin with spare gauge O-ring - part 805052.
Likely 90 durometer as it needs to keep it‘s shape upon compression.

Anyway, leak solved .

Nice! Did you have to screw it in super hard to keep it from leaking?

No the Sekhmet gauge is threaded so that when it’s screwed in snugly (by hand) it faces forward on the v block perfectly. The new O-ring sealed with minimal effort.
Don’t over-tighten, it may disfigure the O-ring.

I have installed a 25mm Sekhmet gauge on my friend's RAW. I just have to install a thicker O ring and everything is fine since then.

Sekhmet had sent this gauge complementary for Testing on various guns.

With a thicker O ring, it is a success on RAW.

Hey Bhaur,
Have you successfully gone to slugs on your RAW’s or are you sticking to pellet?
