Manufactured from ductile iron conforming to ASTM A-536 Grade 65-45-12, this pack fits 4-inch pipe and is rated for a maximum working pressure of 525 psi. A shop coat is applied to the casting at the factory to protect against corrosion during transit and storage. The T-head screw design facilitates proper engagement and even load distribution around the joint. This component is NSF 61 Annex G certified, making it appropriate for use in systems where material safety standards are required. Licensed plumbers and waterworks contractors are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThe ROMAC 248-04 is used in 4-inch mechanical joint piping applications in municipal water and sewer infrastructure. It is suited for both new construction and rehabilitation projects where joint restraint is required to resist thrust forces at fittings, valves, and directional changes. The accessory pack format provides the necessary hardware for a complete restraint installation at a single mechanical joint location. Sewer and waterworks applications are the primary use cases as noted by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLug-style restraint design provides positive joint restraint against thrust separation\u003c\/li\u003e\n  \u003cli\u003eDuctile iron construction per ASTM A-536 Grade 65-45-12 for high strength and impact resistance\u003c\/li\u003e\n  \u003cli\u003eRated to 525 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eT-head screw configuration for uniform clamping force around the joint\u003c\/li\u003e\n  \u003cli\u003eShop coat applied to casting for corrosion protection during transit and storage\u003c\/li\u003e\n  \u003cli\u003eNSF 61 Annex G certified\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 4-inch mechanical joint piping in waterworks and sewer applications.
