NOTE : 1. The above dimensions & weights are for beaded fittings. For measurements of plain fittings (without collar), the nominal mass of fittings may be reduced by 7% (seven percent) from those specified above. Extract from section 2-10 of Indian Standards Specification for melleable cast iron pipe fittings as per 1879:2010
2. The above weights & dimensions are as per IS : 1879:2010 (Part 1 to 10) but to provide our customers, the best & long duration products, We manufacture 'MG' brand fittings with plus dimensions & weights.
'MG' Brand pipe fittings ensures accurate & perfect thread alignment to ensure uninterrupted & free flow of water.
Extra Zinc coating to avoid rust.
High class malleablity to avoid chances
of cracking.
Accurate dimensions to ensure easy assembling leading to saving of time , labour & energy.
The following comparison shows the superiority of 'MG' brand pipe fittings to other
various standard specifications for malleable cast iron pipe fittings applied in different countries :-
