Our stock external expansion tanks and reservoirs are fabricated in copper, fitted with a 15# pressure cap and one or more hose connections.  These are available in both vertical (illustrated) and horizontal styles.

This reservoir is illustrated without a mounting bracket. We have mounting brackets for virtually any mounting configuration. Reservoir is held in position with stainless steel clamps (not shown).

An overflow recovery bottle may be added to a system utilizing these tanks, by connecting to the fill neck tubing fitting provided.

Illustrated here are vertically mounted reservoirs. We also produce horizontal reservoirs with a variety of hose or threaded fittings and replacement expansion tanks for various engine manufacturers' originals.
