Might Need an Additional Gasket
The original sight glass on my Husky air compressor was plastic. Due to tightening, the threads split and started a leak. I chose a steel sight-glass as a replacement. I installed the new glass with the O-Ring supplied, and within an hour I had oil at the bottom of the glass. I ended up getting a larger rubber washer for the steel plug and THAT fixed the leak. It's been dry for weeks now. The sight glass is perfect, you simply might need an additional gasket. I would recommend this item.

Fit
This sight glass fit my Case 580C backhoe. The old sight glass was stained so badly you could not tell the oil level and this part fixed that problem.

great oil level site glass
I have a comet pressure washer pump, the plastic site glass finally broke after 10 years, bought this site glass and a 3/4 inch NPT tap, tapped the hole and screwed in the site glass and back in business

Cheap but works
Not the best quality. Needed a replacement for a Kobalt 30 gal compressor and it worked. Threads were slightly undersized a bit but close enough. A month later, has not leaked. You would want to be careful of how hard you tightened these as they can snap.
