What type of connections are double groove connections used for?

Double groove connections are specifically designed for TPT (Tactical Petroleum Terminal) and low-pressure connections. This type of connection utilizes a double groove design to ensure a more secure and reliable seal when working with fluids at lower pressures, making them ideal for systems that require minimal leakage and a good flow rate, such as those found in tactical operations or certain low-pressure applications.

The double groove design helps in accommodating slight misalignments and provides a larger sealing surface, which enhances its performance in situations where pressure is not a concern. This makes them less suitable for high-pressure pipelines or hydraulic systems, where different types of connections that can withstand greater stresses and pressures are required. Thus, this explains why double groove connections have a specific application best suited to TPT and low-pressure environments.
