PT Coupling

PT Coupling is an American manufacturer of quick connect and disconnect couplings for industrial hoses, with roots dating back to 1951 when R.C. Parrish founded Central Machine & Tool Company as a jobbing machine shop. PT began manufacturing quick connect and disconnect industrial hose fittings in 1955 and started marketing them worldwide in 1960 under the PT Coupling name, establishing a long-standing reputation as a leader in this product category.

The company employs nearly 300 team members across five locations in Oklahoma and one in Mississippi, and operates its own foundry and machine shop facilities. Products are manufactured from a variety of alloys and materials, including aluminum, brass and cast iron, to serve industries such as agriculture, chemical processing, construction, data centers, government, mining, oil and gas, railroad, sanitary, steel processing and transportation. Following several acquisitions, all manufacturing operations were unified under the PT name in 2019, and the company continues to focus on quality products delivered on time at competitive prices.
