1 in (25 mm) Roll Groove Rigid Coupling, Painted | GC25
Available
This AAP roll groove rigid coupling is a painted ductile iron fitting for grooved pipe. It is supplied in 10 sizes, 1 in (25 mm) to 10 in (250 mm).
A rigid coupling joins two grooved pipe or fitting ends. Two housings clamp into the grooves and are tightened with the two bolts listed against each size. AAP names this a rigid coupling. B is the overall dimension and C the housing width, as lettered on the AAP drawing. AAP does not draw or define dimension A, so it is shown as printed.
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.

B and C are lettered on the AAP drawing. AAP does not define dimension A, and the A values for the two smallest sizes are not shown, so A is the dimension to confirm with AIMS if it matters. All dimensions are in millimetres. Weights are approximate, in kilograms per piece. A dash means no figure is shown for that size: AAP does not state it, or AIMS is checking it with AAP.
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. AAP does not say whether a gasket is supplied with the coupling, so confirm this with AIMS before you order.
