OVER FORTY YEARS EXPERIENCE
Since 1954, P/A engineers have been designing
and building equipment for the Metalforming Industry.
Our commitment to provide innovative production
equipment of the highest quality is second to none.
CUP SEAL DESIGN
P/A is the only air feed manufacturer that provides
low maintenance, high-cycle life cup wiper seals on
the main cylinder. Every quality-built air cylinder uses
the same technology as P/A. Cup seals reduce
friction and heat which increases cycle life and
performance by a conservative factor of 50 times.
