The FRP SPIGOT SYSTEM

A universal composite male spigot for fitting to any pipe type.

The FRP spigot requires mechanically fastening, installing backing rod and inserting foam or
grouting between spigot and infield pipe.

This connection although adequate for large diameter pipe is not recommended for outlet
connections on small diameter pipe (300mm or less). The FRP spigot connection reduces
the cross sectional area by as much as 15% on 300mm or less pipe connections. It is
therefore recommended that the ENVIRO-CONNECT tm SYSTEM be used in these
situations.
