US 2010/0019484 A1 · COMPRESSION FITTING ADJUSTMENT SYSTEM

Abstract

The present invention generally relates to a size adjusting device that may be used with compression connectors, such as compression couplings and fittings, that are designed to be connected to at least one duct (such as a pipe or tubing). Such compression connectors are typically comprised of at least one compression member, which is compressed between a casing member and the duct, forming a fluid-tight seal between the duct and the compression connector. The size adjusting device may be positioned between the compression connector and a smaller duct, so that fluid-tight seals are formed between the smaller duct, the size adjusting device, and the compression connector. This allows the compression connector to be connected to ducts that are smaller than the size of duct for which the connector is designed. The present invention also includes methods of use and kits related to the size adjusting device.

Dependent claims

A device comprising:

(a) a casing member, wherein a compression connector is comprised of the casing member and at least one compression member, and the at least one compression member is adapted to be positioned between the casing member and a first duct, so that a fluid-tight seal is adapted to be formed between the compression connector and the first duct by compression of the at least one compression member between the exterior surface of the first duct and the casing member;
(b) size adjusting means adapted for being positioned between a portion of the exterior surface of a second duct and at least a portion of the casing member, and adapted for forming a fluid-tight seal between the exterior surface of the second duct and the size adjusting means, wherein the second duct has a smaller outside cross-sectional perimeter than the first duct and the size adjusting means are comprised of two hollow adjusting compression members adapted to be positioned adjacent to the exterior surface of the second duct;
and
(c) adjuster sealing means for providing a fluid tight seal between the size adjusting means and the casing member.
