  • Major milestones —
  • • In 1951, R.C. Parrish founded a modest machining and drilling operation and named it Central Machine & Tool Company (CMT). He formed the company as a jobbing machine shop, but later recognized that manufacturing a set product line would be the key to building a strong reputation, and ensuring the company's long-term success. At that point he started producing the cam and groove style hose couplings.
  • The Company began manufacturing quick connect/disconnect industrial hose fittings in 1955, and began marketing them worldwide as products of PT Coupling Company, in 1960. PT has long been known as a leader in the production of quick connect/disconnect fittings for the hose industry.
  • • During the early 1960's, CMT expanded and began to supply suspension parts, drive components, and transmission gears for large off-road trucks.
  • • In the late 1960's, a foundry for pouring ferrous and non-ferrous metals, including nodular iron, was added.
  • • In 1984, Oklahoma Investment Casting Company (OICC) was acquired in Blackwell, OK, enabling us to produce complex castings with special heat treating and machining requirements.
  • • In 1990, Specialty Plastics Company was added to the team as a plastic injection molding facility.
  • • PUNCH-LOK® Company was purchased in Chicago, IL and moved to Enid in 1992. PUNCH-LOK® manufactures and distributes various hose clamps, fittings, banding and related installation tools.
  • • In June 2000, ProGrip™ Coupling Company was purchased in Gardenia, CA as a manufacturing facility of crimp sleeves and ferrules for hose fittings and related products. Operations were moved to Enid in 2005 and merged with CMT. The ProGrip™ product line is distributed by PT Coupling.
