ENT conduit fittings are used with ENT pipes in a variety of applications. They facilitate quick, durable concrete-tight installations. The fittings are available in all ENT sizes and transition needs. Their applications are versatile, ranging from linking gaps between ENT tubing and EMT tubing to connecting with metal slab boxes or with rigid PVC.
Made of PVC, the ENT is a flexible, nonmetallic raceway that is used for rigid nonmetallic conduit. It is lightweight, robust, concrete-tight, and resilient to particular conditions. So, you can either bury it directly or install in fire-rated interior walls and concrete slabs. It is also easy to pull cables and wires through the ENT tubing.
Check out some of the different types of ENT conduit fittings:
The couplings do the job of establishing a connection between pieces of several tubing. As they are made of PVC, they are non-corrosive and non-conductive in nature, making it easier to apply them in wet and damp locations.
The lightweight characteristic of the couplings facilitates quick and easy installation. However, you have to use ENT quick set cement while installing, and the couplings are required to be concrete-tight when used with the tubing.
ENT Terminal Adapters
The primary function of the terminal or male adapters is to attach pipes to enclosures or boxes. Both the coupling ends (male and female) make the use of mechanical snap components to connect the fitting to box and tubing. The plus side is you don’t need any solvent cement or tool for the installation.
The terminal adapters come in a wide variety of sizes ranging from 1/2″ to 1″ inches diameter.
ENT to EMT Adapters
The non-metallic ENT to EMT adapter facilitates a smooth transition from ENT to EMT. The polycarbonate material provides added strength and stability to the connections.
ENT Snap-In Adapter
Like other fittings types, the snap-in adapters also perform the function of joining multiple ENT tubing. The PVC material makes the adapter sturdy and resistant to rust and corrosion. As these adapters are suitable for damp and wet locations, you can apply them in a variety of places within home or building.
Available numerous styles, slab boxes are a type of ENT fittings that are completely concrete-tight. They are also engineered tough so you can expect them to last for a long time.
The function of stubbies is to keep conduit ends in place until the concrete is poured and cured. They protect the tubing from any breakage that can be caused at the time of removing the wood forms and take out the necessity of drilling holes in plywood forms.
Besides the abovementioned types, other ENT conduit fittings are also available in other forms such as tapered plugs, ENT clip rings, heavy-duty lock nuts, etc. for various applications. You have to choose the right type based on the size of the conduits and the types of the locations.
