sections of metal raceway shall be made electrically continuous by bonding
jumpers or other means:
• The fitting will be constructed from malleable or ductile iron with
exterior and interior zinc plating for corrosion protection.
• The fitting shall be constructed so that disassembly is not required
during installation.
• The fitting shall be raintight after installation.
• The fitting shall have an internal bonding jumper constructed of a
tinned copper braid, sized to meet UL fault current test requirements
and comply with bonding requirements — NEC Article 250.98

Tighten and you’re ready. No parts to reassemble!
With a wrench, tighten the gland nut to compress the Teflon packing, creating a raintight
seal around the conduit.
