COMP Cams POW351135 Glass Buret 125cc x 0.2cc Combustion Chamber Volume Tool

The COMP Cams POW351135 Glass Buret is a precision measuring instrument designed for accurately determining combustion chamber volume in cylinder heads. With a 125cc capacity and fine 0.2cc graduation increments, this buret delivers the accuracy required for professional engine building and performance tuning applications.

Used as part of the cc'ing process, this glass buret allows engine builders to precisely measure the volume of combustion chambers, piston dome or dish volumes, and deck clearances — critical steps when calculating compression ratio. The clear glass construction allows for easy, unobstructed reading of fluid levels at the meniscus.

Key Features:

• 125cc total capacity — suitable for measuring a wide range of combustion chamber sizes
• 0.2cc graduation increments — fine resolution for precise, repeatable measurements
• Clear borosilicate glass construction — resists chemical attack from calibration fluids
• Clearly etched graduation markings — easy to read under shop conditions
• Compatible with standard combustion chamber cc'ing plates and fixtures
• Essential tool for compression ratio calculation and cylinder head porting work

Whether you're building a high-performance race engine or optimizing a street build, accurate chamber volume measurement is fundamental to achieving your target compression ratio. The COMP Cams POW351135 glass buret is a reliable, professional-grade instrument for any engine builder's toolkit.
