Overall Rating for Schrader 556 High Pressure Strut Coupler - 1/8" NPT Male - 3,000 PSIG
I ordered and received a genuine Schrader valve of good quality. There were cheaper knock-offs available for less money but I wanted the best.
Skygeek's web site showed clear photos and the order form was easy to use. I was happy to receive the exact valve I wanted, shipped where I needed and when I needed it. I couldn't ask for more than that.

This is the right tool
If you are servicing a light airplane strut this tool is essential the old brass goose neck tool lacks the features (Valve depressor) to do the job safely

Adjusting Strut Pressur
This coupler makes a very difficult job comparatively easy. Just be sure the valve compressor is backed out and screw on hand tight. Then screw in valve compressor and it is easy then to add or relieve pressure. Then the valve compressor is screwed out with no loss of pressure in strut. I use it for my tires as well.
ConsIf the connection for the hose was only 1/4" NPT then an adapter would not be needed. I guess the 1/8" is more common for high pressure needs but my cessna does not require high pressure.
