INSTALLATION PROCEDURES
FOR CAST IRON
5. Align the pipe so that it is straight, then push or pull
the spigot through all the sealing rings of the gasket.
Charlotte plain-end pipe is manufactured with beveled
ends to make insertion easy. As the spigot barrel is
forced into the gasket, the gasket is compressed and
completely seals the joint in both displacement and
compression. When seated correctly, you will feel the
spigot end of the pipe “bottom” in the hub.
Installing Fittings with
Compression-Gasket Joints
There are several techniques that may be used to assemble
fitting compression-gasket joints. Review the following
suggestions to determine which best suits your needs.
• Using a Lead Maul: Almost all plain-end fittings may
be installed by driving them into place with a lead
maul or a mallet. After installing and lubricating the
gasket, align the spigot and strike the fitting on its
driving lug, or across its full hub, with a lead maul.
Driving lugs are standard on all Charlotte plain-end
bends and they make joining easy. The fitting may
be struck as hard as necessary, since the lead maul
will deform before damaging the fitting.
Follow all safety procedures in this manual and use
protective eye wear, clothing and equipment when making
any compression gasket joint to reduce the risk of serious
injury.
For large-diameter pipe and fittings (5” - 15”), we
recommend that an adhesive lubricant be used to
ensure a water-tight seal. Adhesive lubricants should
be applied to the inside of the gasket, the outside of
the spigot and the inside of the hub.
To reduce the risk of joint leaks and property damage with
cast iron pipe and fittings in sizes 5” and larger, adhesive
lubricant should be applied to the inside of the gasket and
the outside of the spigot. The use of adhesive lubricant is
not a substitute for proper joint restraint.
