reducing coupling, type 750750
reducing coupling, type 750 >victaulic groove system<
Reducer coupling
Victaulic No. 750
Reducer couplings of type 750 allow direct reduction in the pipeline.
The type 750 reducer coupling replaces two couplings and a reducer and is designed with a
special reducer seal for pressure-dependent sealing.
A steel disk is available on request for vertical pipelines that prevents the smaller pipe from
slipping into the larger pipe.
Material specifications
Housing:
Cast iron according to ASTM A-536, Class 65-45-12.
Cast iron according to ASTM A-395, Class 65-45-15 is available on request.
Coating on the housing: Orange painted.
• Optional: Hot galvanized and others
Seal:
• Class „E“ EPDM
EPDM (colored green). Temperature range –30°F to +230°F /–34°C to +110°C.
Recommended for warm water pipes in the specified temperature range as well as for
a series diluted acids, oil-free air, and many chemicals. UL-approved according to ANSI/NSF 61
for cold (+86°F/+30°C) and warm (+180°F/+82°C) drinking water.
NOT RECOMMENDED FOR PETROLEUM.
• Class „T“ Nitrile
Nitrile (color code orange). Temperature range –20°F to +180°F/–29°C to +82°C.
Recommended for petroleum products, air with oil vapors, vegetable and mineral oils
within the specified temperature range;
but not for hot air over +140°F/+60°C or for warm water over +150°F/+66°C.
NOT RECOMMENDED FOR WARM WATER.
