About C153 push-on fittings

C153 push-on fittings are compact ductile iron fittings: the straight section of the body is left out, so each fitting is shorter and lighter without reducing strength or flow characteristics. The bells use the TYTON JOINT push-on bell design, made by SIGMA under license from the United States Pipe and Foundry Company.

The line covers bends, tees, crosses, wyes, reducers, caps, plugs and adapters. Weights and dimensions for standard fittings are in the catalog.

Highlights

350 psi water working pressure, 4 to 24 in.
Joint deflection up to 5°, per the TYTON JOINT bell design
Standard, bare, FBE and zinc options on the price lists

Questions and answers5 questions buyers ask about C153 push-on 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 TYTON JOINT bell design?

It is the push-on bell these fittings use, made by SIGMA under license from the United States Pipe and Foundry Company. The catalog lists joint deflection up to 5°.

What do the letters around the item number mean?

The base number is the fitting and size: DPB1290 is a 12 in. 90° bend. An E in front means FBE (EDPB1290), a Z at the end means zinc (DPB1290Z) and a B at the end means bare (DPB1290B). A D- in front is the domestic version (D-DPB1290, D-EDPB1290, D-DPB1290Z).

Is there a domestic version?

Yes, from 4 through 24 in. in most fitting types, in standard, FBE and zinc. 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 and zinc are on the price lists too. The Protecto 401 lining and the Tnemec primer are covered by the submittals under Documents; ask your regional team for their price. Not sure what your job needs? Call your regional team.
