FIG. 7307
HDPE Transition Coupling
material specifications
HOUSING:
Ductile Iron conforming to ASTM A 536, Grade 65-45-12
COATING:
Rust inhibiting paint – color: orange
Other Colors Available (IE: RAL3000 and RAL9000)
For other Coating requirements contact a Gruvlok Representative.
ANSI BOLTS & HEAVY HEX NUTS:
Heat treated, zinc electroplated, carbon steel oval-neck track bolts
conforming to ASTM A 183. Zinc electroplated carbon steel heavy hex
nuts conforming to ASTM A 563 Grade A or Grade B, or J995 Grade 2.
GASKETS: Properties in accordance with ASTM D 2000
Grade E EPDM (Green color code)
Service Temperature Range: -30°F to 230°F (-34°C to 110°C).
Recommended for water service, dilute acids, alkaline solutions,
oil free air and many chemical services.
NOT FOR USE IN PETROLEUM APPLICATIONS.
Grade T Nitrile (Orange color code)
Service Temperature Range: -20°F to 180°F (-29°C to 82°C).
Recommended for petroleum applications, air with oil vapor,
vegetable and mineral oils.
NOT FOR USE WITH HOT WATER OR HOT AIR.
For specifc chemical applications, reference the Gruvlok Gasket
Recommendations section of the Gruvlok catalog.
WARNING:
1. Gruvlok products for HDPE pipe must be installed using Gruvlok
XtremeTM Temperature Lubricant.
2. The gasket temperature rating may exceed the manufacturer
temperature rating for the HDPE pipe. Consult the HDPE pipe
manufacturer for the temperature and pressure ratings.
The Gruvlok Figure 7307 HDPE transition coupling allows for
transition from HDPE pipe or fttings to grooved-end pipe
prepared per Gruvlok standard cut or roll groove specifcations
for steel pipe or Gruvlok fttings. The Figure 7307 incorporates
two banks of machined teeth on one side of the housing, and
a key section on the other, that engages specifcally grooved
steel pipe or fttings. The banks of teeth are positioned away
from the gasket enhancing the sealing ability of the gasket. The
temperature and pressure capabilities of the Figure 7307 exceed
the highest temperature and pressure ratings of the HDPE pipe.
The Figure 7307 features a
low profle contoured
housing with a ramp along the
outside diameter on the half of the
HDPE coupling. This easy to assemble
mechanical joint is used to join HDPE pipe (conforming to ASTM D 2447, D 3000, D 3035, or
F 714) to roll grooved or cut grooved standard weight and, roll grooved lightweight pipe, as
well as with grooved-end fttings and valves. The coupling can be used with HDPE pipe
having SDR values of 7.3 to 32.5.
