Doubts

1) Material of Tupy’s pipe fittings
TUPY’s pipe fittings are manufactured in black malleable iron according to NBR 6950’s specifications.

2) TUPY’s pipe fittings applications
TUPY’s pipe fittings are recommended for water, gas, vapor, liquid fuel (diesel, gasoline and alcohol) and gas fuels (Liquefied Petroleum Gas and Natural Gas).

3) Standards conformity
TUPY’s pipe fittings are manufactured in accordance with ABNT’s technical standard specifications:

NBR 6943 – malleable cast iron pipe fittings with NBR NM ISO 7-1 thread for pipes (for use in pipes according to standard NBR 5580);

NBR 6925 – malleable cast iron pipe fittings with NPT thread for pipes (for use with pipes according to NBR 5587).

4) Working Pressures to which TUPY pipe fittings resist – you may know through the table below:
