You Need To Consider:what type of cylinder

Some choices are:

repairable Air cylinder or "throw-away" non-repairable types

NFPA cylinders (north American standard) or ISO cylinders (European standard)

aluminum, steel, stainless steel, composite construction

steel rod, stainless steel rod, chromed rod

Usually, as the bore size of the cylinder gets larger the style opted for is a repairable type, as more money will be spent on acquiring the cylinder therefore the cost for repair becomes a smaller percentage of the overall cost. It's hard to get excited about trying to fix a $80.00 cylinder when the parts cost $30.00 and it will take a worker two hours to fix it. On the other hand, if the cylinder costs $500.00 - a different story.As the bore size of the cylinder changes, so too will the rod diameter and rod threads, and the port sizes.NFPA cylinders are imperial dimensions and imperial threads, ISO cylinders are metric dimensions and threads.You need to consider the conditions into which the cylinder will be installed to determine if you need specialty materials in their construction. Also, specialty seals may be required in corrosive, low or high heat environments.
