Abstract
An adapter assembly for a well system includes at least one coupling member having a passage formed therein and an adapter including a neck duct formed thereon. The neck duct is received in the passage of the coupling member forming a substantially fluid-tight seal therebetween. At least the adapter is formed from a lead-free material, minimizing a weighted average lead content of the adapter assembly.
Claims20
An adapter assembly for a well system, comprising:
- an adapter configured to be disposed in a casing of a well, the adapter including an outwardly extending duct, wherein the adapter cooperates with a first coupling member to facilitate a flow of a fluid from the well, wherein the adapter includes at least one of a substantially planar mating surface located on a face of the duct and a housing formed from a substantially lead-free material, and wherein a weighted average lead content of the adapter assembly with respect to wetted surfaces of the adapter and the first coupling member is no more than about 0.25 percent.
An adapter assembly for a well system, comprising:
- an adapter configured to be disposed in a casing of a well, the adapter cooperates with a first coupling member to facilitate a flow of a fluid from the well, wherein at least one of the adapter and the first coupling member is formed from a polyphenylene ether-polystyrene blended plastic material.
A method of forming an adapter assembly for a well system, comprising the step of:
- forming an adapter from a polyphenylene ether-polystyrene blended plastic material, wherein the adapter is configured to be disposed in a casing of a well.
