Electrical conduit fittings including connectors, adapters and couplings allow for quick and easy RTRC installations.
There are many lightweight fitting types available for both IPS (iron pipe size) and ID (inside diameter) type conduit in a variety of sizes, including:
- Standard Wall (SW), thickness .070″
- Medium Wall (MW), thickness .096″
- Heavy Wall (HW), thickness .110″
- Extra Heavy Wall (XW), thickness .250”
All Champion Fiberglass® fittings come standard in black and gray but can be completed with custom colors upon request.
Champion Fiberglass fittings are certified and manufactured in compliance with:
- UL 2420 (Below Ground) listed
- UL 2515 (Above Ground) listed
- ISO 9001:2015 Certified
- ISO 14001:2015 Certified
- ISO 45001:2018 Certified
Types of Conduit Fittings
A box connector creates a separable termination into a box. This connector has straight threads (NPS) and is supplied with a locknut; a sealing O-ring may also be used. Box connectors are available with or without an internal gasket.
What sizes of straight thread box connectors are available?
Champion Fiberglass box connectors are available in trade sizes 3/4” to 6” for use above and below ground. For more information please refer to the Champion Fiberglass Duct catalog.
Male adapters with tapered threads (NPT) are generally used for joining to female threads of rigid steel, Myers-type hubs or terminating into precast iron boxes with female thread entrances. Special adapters for PVC-coated fittings are also available with tapered threads and a straight shoulder so that they can fit under the PVC sleeve of a PVC-coated steel fitting.
What sizes of male adapters are available?
Champion Fiberglass male adapters are available with or without a gasket in trade sizes 3/4” to 6” for use above and below ground. For more information please refer to the Champion Fiberglass Duct catalog.
Female adapters are generally used for joining fiberglass conduit with galvanized rigid steel (GRS) conduit. They have the same threads as GRS conduit and can easily be attached to GRS conduit.
What sizes of female adapters are available?
Champion Fiberglass female adapters are available with or without a gasket in trade sizes 3/4” to 6” for use above and below ground. For more information please refer to the Champion Fiberglass Duct catalog.
Champion Fiberglass manufactures a variety of coupling types including:
- Sleeve couplings (with or without gasket)
- Stop couplings (with or without gasket)
- 5° double bell couplings (with or without gasket)
- Custom angle double bell couplings (with or without gasket)
Expansion Joint Fittings
Expansion joints are required when the duct is longer than 50 feet. For duct between 50 feet to 200 feet, one expansion joint should be installed at the midpoint. For duct longer than 200 feet, one expansion joint should be installed every 200 feet apart. Champion Fiberglass manufactures the following duct expansion joint types:
- Single Expansion Joint Socket X Spigot (with or without O-ring)
- Single Expansion Joint Socket X Socket (with or without O-ring)
- Double Expansion Joint (with or without O-ring)
- Alignment/Expansion Fittings (also known as expansion/deflection joints)
End bells are used for creating a permanent termination into a box and have a smooth surface that the cable can be pulled over. Champion Fiberglass end bells are available with or without the gasket.
What sizes of fiberglass end caps are available?
Champion Fiberglass end caps are available in trade sizes 3/4” to 6” for use above and below ground. For more information please refer to the Champion Fiberglass Duct catalog.
Split Anchor Rings
Split anchor rings are always supplied in pairs and are used for above-ground installations in order to create fixed points. The split anchor rings are placed around the hanger closest to the midpoint between two expansion joints. One pair of split anchor rings is placed on each side of the hanger. The split anchor rings are bonded with epoxy adhesive to the outside of the conduit. The hanger where split anchor rings are used is called an anchor hanger and is normally braced.
What sizes of split anchor rings are available?
Champion Fiberglass split anchor rings are available in trade sizes 3/4” to 6”. For more information please refer to the Bridge Hangers section of the Champion Fiberglass Duct catalog.
Thermoplastic plugs are lightweight plastic plugs that “press-fit” into the conduit or elbow ends to keep out debris.
Slip collars allow unrestricted expansion/contraction movement of RTRC conduit while still providing proper support to the conduit system. The slip collars eliminate the expansion/contraction binding that naturally occurs in traditional pipe clamp installations. Champion Fiberglass slip collars can be used with steel or fiberglass pipe clamps and are available in heavy-duty wall thickness to allow for considerable pipe clamp tightening without any force transfer to conduit.
When the cable cannot be removed for field repairs, Champion Fiberglass offers split duct conduit. The duct is split lengthwise in two halves, making installation easier. The duct is then joined by using thermoplastic H-strips. Cable ties are applied every 2–3 feet for securing the duct. Champion Fiberglass also offers elbows and fittings in split configuration.
Reducing adapters are used to reduce between different diameters of conduit. They are available in a wide variety of sizes from 3/4” to 1/2” reducers to 6” to 5” reducers.
Transition adapters are used to transition from fiberglass to PVC SCH 40/80. They are available in a wide variety of sizes including 3/4” to 8”.
Wobble couplings are used for minor vertical and horizontal offsets for above-ground installations.
