Masport Manway
Each Masport Manway incorporates a
one-piece, low-profile flanged dome
lid design to eliminate possible leaks
found in two-piece lid designs. The
cut-resistant nitrite gasket keeps
retaining seat. Durable ductile
iron wing nuts with captive wear
washers have a wide span to easily
hand tighten or loosen. A stepped
shoulder design on the wing nut
provides a positive lock into the lid
closure bracket for superior lid-toweld
collar alignment and safety. All
weld collars are constructed of 1/4”
thick hot rolled steel for extra long
life. Each Masport Manway is rated
for 15 P.S.I. working pressure and
expertly mig welded in close tolerance
fixtures for consistent high quality.
