Tubing Precision
inside diameter without the expense or delays of honing
operations.
Precision tooling
developed and maintained by Amalga Composites is a
critical element in providing the close tolerance
pressure tubing you demand. Cylinder tubing offered by
Amalga Composites has the following inside diameter
characteristics that improve piston performance. The
table provides geometric characteristics and tolerances
for the range of diameters available.

Cutting
Composite tubing
produced by Amalga Composites is cut to blueprint
specified lengths. Depending on the tube diameter, either
a horizontal stroke or abrasive cut off saw is utilized.
Chamfers, Shoulders
and Grooves
Amalga Composites
can offer a cylinder body that is completely machined and
ready for assembly.
