The TODO-MATIC® dry break coupling range is a market-leading solution for safe, spill-free fluid transfer across oil, gas, chemical, and petrochemical applications. Designed with a valve-protected mechanism, this dry break coupling minimizes residual loss and delivers virtually zero spillage, improving operator safety and maximizing efficiency.
Developed from over 30 years of proven industry experience, TODO couplings were among the first to meet strict military standards such as NATO STANAG 3756 requirements. Their robust design ensures minimal residual loss, virtually zero spillage, and reliable performance in demanding environments.
A dry break coupling is an industrial connection system that prevents fluid loss during connection and disconnection. Unlike conventional systems, both sides remain sealed until securely connected, ensuring no product escapes.
These dry break fittings are widely used for handling hazardous, high-value, and sensitive fluids where safety, reliability, and cleanliness are critical.
TODO-MATIC dry break couplings are designed to operate under harsh conditions and remain reliable even after repeat use. All units have a working temperature range of -20°C to +80°C (-4°F to +176°F), covering virtually every application in the field. Working pressures vary according to the material used.
Please note that working pressures are reduced for flanged products according to their individual pressure rating. For example, PN10/16 flanged products are reduced to 16 bar in stainless steel.
Up to 25 bar (363 psi)
Up to 37.5 bar (544 psi)
-20°C to +80°C (-4°F to +176°F) standard;
-45°C to +150°C (-49°F to +302°F) options
The TODO-MATIC® dry break coupling is recognized as a best-in-class solution for safe, reliable fluid transfer:
This combination of safety, durability, and efficiency makes TODO a trusted solution for dry break fittings worldwide.
