Female-Female Couplings & Adaptors (Zone 1 and 2) RAM

The adaptors and plugs are normally used in the chemical and pretrochemical plants, off-shore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present.

Unit Of Measurement (UOM):

The RAM couplings are used to convert a male hub into an equivalent or reduced or increased female hub. The RAM fittings with same diameter size and thread type on both sides are used to connect conduits with threaded ends. The adaptors (reducers/enlargers) are used to provide means of connection between same or dissimilar thread forms (e.g. NPT to Metric).

RAM Female-Female Couplings & Adaptors

The plugs are normally installed on Ex d and Ex e enclosures to protect the internal equipment by the penetration of liquids and dust before the installation of the conduit fittings and cable glands. They also allow the presence of spare hubs on the enclosure to be used in case of future expansions. The adaptors are used to resolve all the problems connected to the conduit installation as joints and direct connections of equipment with different sizes of threads and/or different types of thread. The adaptors and plugs with cylindrical threads are equipped with O-ring to grant an IP 66/68 protection to the enclosure.

The materials used to manufacture the adaptors and plugs have been studied to grant the maximum protection against the highly corrosive agents present in these industries.
They are available in:
• brass
• nickel-plated brass
• galvanized steel
• stainless steel AISI 316
The O-ring are made of neoprene and, for low and high temperature environments, of silicone.
The design of all the adaptors and plugs includes the presence of a hexagon shape to facilitate the installation and to grant the correct tightening level.
All the equipment have the double marking for Ex d and Ex e installations with the sole exception of the components threaded with PG – DIN 40430 that are available only for Ex e installations.
