Our History

M&M International's rich heritage spans across four generations in the oil and gas industry and three generations in precision machine metal working.


M&M International was established.

In 1980 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.

M&M International received the patents for CANISTER GUARD®, SURE-STOP™, CHECK-SEAL™, and LITE-TORC™.

In 1990, M&M International received 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.

CANISTER GUARD® technology quickly brought M&M to the forefront of the well control valve sector.

The 2000’s ushered in a period of fantastic growth for M&M International.  Our CANISTER GUARD® technology quickly gained industry-wide recognition and brought M&M to the forefront of the well control valve sector.  Customers in both the onshore and offshore drilling spaces came to rely on the functionality and durability of the CANISTER GUARD®.  Many crucial additions in personnel, equipment, and facilities were made during this time in response to the strong demand seen from our loyal customers and the market as a whole.

M&M International outgrew its 52,000 sq. ft. building and moved to a larger, perfectly tailored 118,000 sq. ft. facility to accommodate its growth.

The 2010’s brought new and exciting opportunities for M&M International to incorporate its expertise in valve technology into other products needed by the industry.  Many specialized valve and well control products were designed and manufactured by the M&M Team during this period, solidifying the company as a reliable problem solver when it came to well and pressure control issues.  In 2012, M&M constructed a 52,000 square foot addition to accommodate for growth, and by 2018 the company had outgrown its long-time home and moved to a larger facility.  Once the move was complete, M&M International would occupy approximately 118,000 square feet of facility and would have a foundation on which to build for many years to come.
