Questions and answers5 questions buyers ask about C110 MJ fittings

Where do I find the price?

On SIGMA's price lists. Where an item is on a posted list, the View price list button near the top of this page opens it, and every posted list is on the Price Lists page. SIGMA sells through waterworks distributors, and your distributor sets your price. For contract pricing, ask your regional team.

What is the difference between C110 and C153 fittings?

Both are AWWA ductile iron fittings with mechanical joint ends. C110 fittings are full body, so they are longer and heavier. C153 fittings are compact: the straight section of the body is left out, so they are shorter and lighter. If your spec calls for compact fittings, see C153 MJ fittings.

What do the letters around the item number mean?

The base number is the fitting and size: XMB1290 is a 12 in. 90° bend. An E in front means FBE (EXMB1290), 4- in front means Protecto 401 (4-XMB1290), a Z at the end means zinc (XMB1290Z) and a B at the end means bare (XMB1290B). A D- in front is the domestic version (D-XMB1290, D-EXMB1290, D4-XMB1290).

Is there a domestic version?

Yes, from 2 through 48 in. in most fitting types. Pick Domestic above and the item number and price list switch to it. Fittings and sizes that are not on the domestic price list are grayed out.

Which coating should I pick?

The one your spec names. Standard import fittings are double cement lined with an asphaltic seal coat inside and out. FBE, Protecto 401 and zinc are on the price lists too. For the Tnemec primer in the submittals under Documents, ask your regional team for a price. Not sure what your job needs? Call your regional team.
