Claim 8:
9. A fitting for a pipe comprising:
a cylindrical sleeve comprising a gripper at a proximal end of the sleeve, wherein the gripper has a first inner diameter in an unsealed configuration and a second inner diameter in a sealed configuration, wherein the gripper comprises a plurality of gripper rings, wherein the first diameter is greater than the second diameter; and
a spigot disposed concentrically within the sleeve and having an outer surface sized to fit within a proximal end of the pipe,
wherein the sleeve is slidable along the spigot in a proximal direction to move from the unsealed configuration to the sealed configuration,
wherein, the inner surface of the gripper and the outer surface of the spigot define an annular space with a first radial width sized to accept insertion of the proximal end of the pipe, and
wherein, when the sleeve is moved with respect to the spigot in the proximal direction toward a sealed position, the gripper is inwardly compressed from the first diameter to the second diameter.
