2 x 1-1/2 in Roll Groove Concentric Reducer, Painted | GCR5040
Available
This AAP roll groove concentric reducer is a painted ductile iron fitting for grooved pipe. It is supplied in 11 sizes, 2 x 1-1/2 in (50 x 40 mm) to 8 x 6 in (200 x 150 mm).
A concentric reducer joins two grooved pipe ends of different sizes on the same centre line. Both ends are grooved to take a roll groove coupling. Sizes are listed larger first, then smaller. A is the length, as lettered on the AAP drawing.
AAP states that its roll groove fittings are made in ductile iron to ASTM A536 Grade 65-45-12 (manufacturer-stated). AAP lists this version as painted and does not state the paint type or colour. AAP states that roll groove suits standard pipe with cut grooves, or standard and light wall pipe with rolled grooves (manufacturer-stated). AAP states a working pressure of 2500 kPa and a maximum working temperature of 100 °C for this product (manufacturer-stated). Working pressures may also be limited by pressure piping codes or industry regulations, so confirm the pressure and temperature for your application with AIMS before you order.

Selecting the right option
Choose the size to match your pipe. AAP lists the pipe outside diameter for each size in its roll groove specification, so check your pipe has that outside diameter and is grooved to AAP's groove dimensions. Each grooved joint also needs a roll groove coupling, which is listed separately.
