Ductile Iron Fittings.

Both are AWWA ductile iron fittings. C153 fittings are compact: the straight section of the body is left out, so they are shorter and lighter. C110 fittings are full body, so they are longer and heavier. Your spec says which one the job takes.

Yes. Domestic C153 MJ fittings run 3 through 48 in. in most fitting types. Pick Domestic on the C153 MJ page to see the item numbers. Domestic item numbers start with D- (D4- for Protecto 401), as in D-DMB1290.

The one your spec names. Standard import C153 and C110 MJ fittings are double cement lined with an asphaltic seal coat. C110 flanged fittings are red primer outside, and the MJ Connector is e-coated. FBE, Protecto 401 and zinc each have their own price list and submittal; the Coatings and Linings page explains each coating. Not sure what your job needs? Call your regional team.

Mechanical joints on ductile iron pipe take a ONE-LOK restraint such as SLDE. PVC pipe takes ONE-LOK SLCE or PV-LOK. The Restraint Calculator works out the restrained length for each fitting.

A heat code lets a fitting's metallurgical properties be traced and verified. SIGMA's fitting catalogs state that all fittings are heat coded and hydrostatically tested to SIGMA's Quality Management Standard. For domestic fittings, ask your regional team.
