Grates
The grates, and the castings for the same, provided by Specified Fittings have been tested and certified by the foundry to meet or exceed standards set forth in ASTM A535 Grade 60-40-18 and ASTM A48-83 65-42-12 as required by specifications.
About our locked-in gaskets
Specified Fittings' locked-in gasket is quickly and easily joined together by simply inserting the spigot end of the pipe into the bell socket of the fitting. Multi-lip design of the sealing gasket provides a positive seal that is pressure and vacuum tight. Retained ring design prevents fishmouthing or dislocation of the gasket. Sealing gasket is exceptionally smooth and completely free of core marks. Selection of the correct material to be applied to a sealing system will depend not only on the characteristics of the fluid to be contained but also the properties of the surrounding environment.
