Cast Iron Installation
INSTALLATION PROCEDURES
FOR CAST IRON
Making A Compression-Gasket Joint
1. Clean the hub and spigot so they are free of all dirt,
mud, sand, gravel, and other foreign materials.
2. Remove sharp edges by filing or tapping with a ball-
peen hammer. Insert the gasket into the hub. This
may be done by using one of three methods.
• Drive-In: Place the gasket into the hub as far
as possible, then tap the gasket’s outer lip with
a rubber mallet or flat board until it becomes
seated. This method works best on two- or three-
inch gaskets.
3. Regardless of which insertion method you use, the
gasket must be completely inserted into the hub.
Only the gasket’s flange that shows identification
information should remain exposed outside the hub.
• Double Folding: Squeeze the gasket together
with both hands, then insert it into the hub. As
you withdraw your hands, the gasket will unfold
and snap into proper position.
• Thumb Fold: Hold the outside circumference
of the gasket and press thumbs down and in, as
though turning the gasket inside out. Place the
gasket into the hub and release it, allowing it to
snap into proper position.
4. Lubricate the gasket following the pipe joint
lubrication manufacturer’s recommendations. For
small-diameter pipe and fittings (2” - 4”), coat the
inside of the gasket with lubricant using a paint brush
or rag, and then coat the outside of the spigot.
To reduce the risk of serious injury:
• Keep pipe joint and adhesive lubricant from touching
eyes or skin.
• Only use adhesive lubricant with proper ventilation.
• Read and carefully follow the manufacturer’s application
and safety instructions, particularly when working
around sources of heat, sparks or open flame.
• In case of an accident, follow hazardous warning and
medical treatment statement shown on the product’s
label.
