M&M International is a family owned and operated original equipment manufacturer specializing in high-pressure kelly valves, safety valves, top drive valves, and inside BOP valves utilized during the exploration, completion, and production of oil and natural gas wells.

Our History

End to end, M&M International’s familial history stretches back over four generations in the oil field and three generations in machine metal working.



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.
