About this file
This document is a manufacturer's submittal information sheet for the Romac XR501 Extended Range Coupling, potentially related to a Michigan state and local contract opportunity for coupling transitions. The product is a versatile pipe coupling designed for multi-purpose use, capable of connecting SDR 35 PVC sewer pipes through Class 200 A/C pipe sizes, with working pressures up to 260 psi when installed on standard steel pipe and larger. The coupling meets AWWA Standard C219 specifications and can be NSF 61 and NSF 372 certified upon request.
The coupling is constructed with ductile (nodular) iron end and center rings meeting ASTM A 536 Grade 65-45-12, EPDM rubber gaskets compliant with ASTM D2000, and 5/8 inch high-strength low alloy steel trackhead bolts. Key technical specifications include corrosion-protective shop coatings, the ability to accommodate various pipe sizes, and optional stainless steel bolt configurations. The document emphasizes that for pipe outer diameters smaller than standard steel, the coupling should not exceed 20 PSI of pressure, which may be an important consideration for the potential Michigan procurement process.

MATERIALS
CASTINGS
The end rings and center rings are cast from ductile (nodular) iron, meeting or exceeding ASTM A 536, Grade 65-45-12.
GASKETS
Made from virgin Ethylene Propylene Diene Monomer Rubber (EPDM) compounded for water and sewer ser-vice in accordance with ASTM D2000, NSF 61 Certified.
Other compounds available upon request.
BOLTS AND NUTS
5/8 inch, High strength low alloy steel trackhead bolts.
National coarse rolled thread and heavy hex nuts. Steel meets AWWA C-111 composition specifications. Stain-less steel bolts and nuts available on request.
COATINGS
Shop coat applied to cast parts for corrosion protection in transit. Fusion bonded epoxy, liquid epoxy and other coatings available on request.
When properly installed on standard steel pipe and larger the Romac Style XR501 coupling can be used at working pressures up to 260 psi. Higher working pressures available for specific applications. NOTE: for pipe ODs smaller than standard steel do not exceed 20 PSI.
Provides an Extended Range Coupling for multi-purpose use. One gasket, center ring and end ring for SDR 35 PVC sewer through Class 200 A/C pipe sizes. NOTE: for pipe ODs smaller than standard steel do not exceed 20 PSI.
Romac 501 couplings meet the specifications set forth in the AWWA Standard C219 coupling spec.
