Description: A method is provided for installing a valve seat in the hole of a valve element. The valve seat is fabricated from a seal material having a freezing temperature. The seal material is stretched such that a portion thereof has a reduced diameter that is less than the diameter of the valve element's hole. The stretched portion of the seal material is immersed in a first environment having a temperature that is less than the freezing temperature of the seal material to thereby freeze the stretched portion and fix its reduced diameter. The stretched and frozen portion is then placed in the valve element's hole with the combination then being placed in a second environment having a temperature that is greater than the freezing temperature of the seal material.
