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 mission is to save lives and preserve the environment by engineering, designing and building the smartest solutions possible.

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 moved our main manufacturing operations to M&M International’s present location in Broussard, LA and began focusing on developing the CANISTER GUARD®, SURE-STOP™ and CHECK-SEAL™ technologies into a viable, salable product. In 1995, our company officially changed to M&M International. In 1997, the patent for our LITE-TORC™ technology is received.


The 2000s have been a period of steady growth and expansions 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.
