SIGMA announces wide availability of Swivel Anchoring Reducers

SIGMA developed the Swivel Anchoring Reducer to provide contractors and municipalities with a compact solution for hydrant replacements. Because old mains often contain undersized pipes measuring 4", compatibility issues may arise in the field. These occur when technicians attempt to connect replacements to most standard hydrant shoes, which generally contain 6" MJ (mechanical joint) connections.

The SIGMA Anchoring Reducer, (SIGMA Part #SMR64) delivers the benefits of the SIGMA SSA swivel- type adapter coupling (known as an "anchor coupling" throughout the industry) and incorporates it into a 6x4 small end MJ reducer. The result is an anchoring reducer that has a 6" swivel anchor x 4" MJ bell. SIGMA's Engineering Team brought further innovation to this product by opening up the 4" MJ bell to accommodate most sizes of 4" pipe commonly found in use today. In addition, the SIGMA Anchor Reducer is compatible with most oversized applications.

Building on the success of the SIGMA Anchoring Reducer, we also developed a 6”x 8” version with the MJ on the larger end (SIGMA Part #LMR86).

Both products comply with all ANSI/AWWA C153/A21.53 standards, meet a pressure rating of 350psi, and display cast marks and heat numbers per SIGMA’s industry-leading quality assurance protocols.

The products lend themselves to everyday uses in the field. They eliminate the need to restrain a plain-end fitting with a wedge action restraint, which some restraint and fitting manufacturers do not recommend.
