About Us

MMC International Corporation primarily manufactures equipment and instrumentation for use in the hazardous or potentially hazardous environments found aboard petroleum and petro chemical facilities.

World leading in the supply of gauging and sampling systems.

The firm maintains sales and service offices in the USA, UK and Japan as well as a global network of MMC authorized repair agencies.

Since 1950

The enterprise that became MMC started in the early 1940s as the Marine Plastics Corporation, making deck surfacing for tankers and military vessels. After the close of World War II, the name was changed to the Marine Moisture Control Company to reflect the firm’s rapid expansion as a manufacturer of equipment for the removal of moisture from shipboard machinery and cargo spaces.

Over the next several decades, MMC devices–such as its corrosion-preventing gear case dehydrators–became standard components throughout the world’s fleets of tankers.

The MMC product line continued to expand with lube oil clarifier coalescers, hydraulic valve systems, draft-indicating and tank-gauging systems, cargo-handling hose couplings, and other crucial items required by petroleum and chemical transport vessels.

In 1972, MMC pioneered solid-state electronic gauging equipment for use in hazardous shipboard environments. That new line of equipment was designed to meet the emerging international standards of explosion-proof or flameproof safety in the petroleum and chemical transport fields. Today, this category of highly specialized safety gear is referred to internationally as “Intrinsically Safe Equipment” and MMC remains a state-of-the-art leader in the field it helped invent. Since the 1970s, MMC’s Intrinsically Safe Equipment products have been approved by international certifying agencies such as Factory Mutual, CSA, SAA, EECS, NKK, NK (Japan) and HK.

By the 1980s, MMC’s product line had grown to include mechanical, electro-mechanical and electronic monitoring and safety equipment used by industrial facilities involved in the transport, storage and processing of a wide variety of chemicals. In addition, the firm’s technology was adapted for environmental monitoring purposes, spawning yet another new product line beyond the maritime field.


Thus, by 1990, the company changed its name to MMC International Corporation to more accurately reflect the diversity of its product lines, the broad base of its technological research goals, and the global reach of its sales operations
