    The 4MA series cylinder is a ruggedly constructed, highly configurable, all purpose design. The aluminum body and machined aluminum end caps make the 4MA a light weight solution. With 8 bore sizes, 20 NFPA mounting styles, and a variety of other options the 4MA is easily adaptable to practically any application. Carboxilated nitrile seals, a urethane rod wiper, and piston wear band combine to offer low friction, leak free operation, and long service life. To minimize downtime when maintenance is required, the externally removeable bronze gland enables servicing of the cylinder without disassembly of the body. The 4MA series cylinder has a full range of features and options.
