ASTM A193 Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

Application: S2000 Master Cylinder
K-Tuned CMC Reservoir is a direct replacement for S2000 CMC. Machined from 6061 aluminum it offers the same volume as OEM. The double o-ring seal ensures no chance of leak. Set screws lock the reservoir in place once located. The diaphragm allows fluid movement without letting air interact with brake fluid. This is crucial as brake fluid is hygroscopic (absorbs water from the air) which can cause premature clutch fatigue and overheating.
This can be changed without re-bleeding clutch system. First, place an absorbent towel or cloth below the CMC. You do not want brake fluid to come in contact with any paint. Using a syringe or absorbent towel you can slowly suck up the fluid inside the reservoir. Once the brake fluid is low enough you can remove the stock reservoir. Place a small amount of lube/oil on the o-rings before installing. Slowly press the new reservoir onto the CMC ensuring not to pitch or tear an o-ring. Once installed use the set screws to lock the CMC into place.
Using a rag or shop towels to absorb fluid inside original reservoir first.. Place a thick absorbent towel below master to ensure any leaks don’t come in contact with paint.
