Cut Sheet
All female ends of PVC coated conduit fittings shall have a flexible PVC
sleeve which extends from the female ends of the fitting and which will
overlap the PVC coating on the conduit when the fitting has been installed
on the conduit. The length of the sleeve extension(s) shall be at least
equivalent to the nominal conduit size for sizes up through 2”. For sizes 2”
– 6”, the length of the sleeve extension(s) shall be at least 2 in. The PVC
sleeve shall be a nominal thickness of 40 mils in thickness. The inside
diameter of the overlapping sleeve shall be less than the outside diameter
of the PVC-coated conduit.
1. The PVC coating on all form 8 covers shall form a gasket-like
flange of at least 5/16” wide and minimum 40 mils covering the top
of the fitting around the opening and the bottom of the
cover/matting with the flange of the fitting.
A blue urethane coating shall be uniformly and consistently
applied to the interior, exterior and threads of all conduit bodies,
including but not limited to, form 8 and form 7 conduit bodies.
This coating shall be a nominal 2-mil thickness.
Stainless steel encapsulated screws shall be supplied with all form
7 and form 8 fittings.
2. Rigid Hubs shall have a nominal 40 mils PVC coating thickness
with a nominal 2 mils of blue urethane on interior and threads. The
male threads and locknut of the hub shall remain uncoated.
3. Liquid-Tight fittings shall have an exterior PVC coating of a
minimum thickness of nominal 40 mils.
D. PVC COATED HAZARDOUS LOCATION FITTINGS:
Hazardous location fittings, prior to PVC coating must be UL listed.
All female ends of PVC coated conduit fittings shall have a flexible PVC
sleeve which extends from the female ends of the fitting and which will
overlap the PVC coating on the conduit when the fitting has been installed
on the conduit. The length of the sleeve extension(s) shall be at least
equivalent to the nominal conduit size for sizes up through 2”. For sizes 2”
– 6”, the length of the sleeve extension(s) shall be at least 2 in. The PVC
sleeve shall be a nominal thickness of 40 mils in thickness. The inside
diameter of the overlapping sleeve shall be less than the outside diameter
of the PVC-coated conduit.
E. PVC COATED STRUT, HANGERS, AND CLAMPS:
Right angle beam clamps and U-bolts shall be specially formed and sized
to snugly fit the outside diameter of the PVC coated conduit. Support
products such as ferrous strut, beam clamps, pipe straps, clamp back
