  • Patent number: 6457718
    Abstract: A pipe gasket and a method of forming a pipe joint between a metal spigot pipe and metal belled pipe. The gasket has three regions to facilitate a seal. A seal region forms the primary seal within the groove of the belled pipe. A sleeve region extending from the seal region forms a sleeve around the end of an inserted spigot pipe to protect the pipe from contact with fluids flowing there through. A retainer region coupled to the sleeve region covers the end of the spigot pipe and also acts as a stop to prevent over-insertion of the spigot pipe into the belled pipe. The three regions cooperate to form a sleeve around the spigot pipe end and to prevent over-insertion of the spigot pipe into the belled pipe.
