In 1984 M&M International (formerly M&M Supply Company) was established by brothers D. John McKnight and Brent H. McKnight with a primary focus on the manufacturing and sales of our Standard Two-Piece Kelly and Safety Valves, as well as Inside Blowout Preventers and various other drill-stem accessories.
In 1990, M&M International received the United States patents for CANISTER GUARD®, SURE-STOP™ and CHECK-SEAL™ applications & technologies. Soon after, M&M International began focusing on developing the CANISTER GUARD®, SURE-STOP™ and CHECK-SEAL™ technologies into a viable, salable product. In 1995, our company officially changed its name to M&M International. In 1997, the patent for our LITE-TORC™ technology was received.
The 2000s were a period of steady growth and expansion for M&M International. In 2012, M&M constructed a 52,000 square foot addition with 27,000 square feet of new building space to accommodate a new raw material yard, additional manufacturing, additional small parts inventory capacity, and increased hydrostatic testing capacity, as well as adding make-up and break-out capabilities.
In 2018, M&M International moved to a new facility.
