SIGMA Anchoring Reducer eases connections between older, 4” mains, and new standard issue 6” mechanical joints

SIGMA’s Engineering Team developed the Anchoring Reducer to provide contractors and municipalities a compact solution for hydrant replacements. As the infrastructure of many municipalities ages, contractors are required to accommodate and service older mains, which often contain undersized four inch pipes.  Issues may arise in the field when technicians attempt to connect these older mains to the standard equipment of today, which generally contain six inch mechanical joint connections.

The SIGMA Anchor Reducer (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 6×4 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 provide by opening up the 4” MJ bell to accommodate most sizes of 4” pipe commonly found in use today. This product is also offered in a larger size, with an 8” MJ Bell and a 6”Anchor (Part #LMR86).

The SIGMA Anchor Reducer is compatible with most oversized applications, and it also lends itself to everyday applications in the field. It eliminates the need to restrain a plain-end fitting with a wedge action restraint, which some restraint and fitting manufacturers do not recommend.
