standard flexible coupling77.
standard flexible coupling type 77, PN 69 >victaulic groove system<
Flexible standard coupling
Victaulic No. 77
Flexible grooved standard couplings allow controlled linear as well as angular and rotary motion
at all connection points to compensate for expansions/contractions, settling, vibrations, noises,
as well as other motions of the pipe system.The couplings reinforced with cross ribs of type 77
are designed as especially robust components for pipe systems.
All sizes are delivered with galvanized screws and nuts.
The housings are also available in galvanized and stainless steel versions.
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.
