The Gruvlok Figure 7305 HDPE Coupling is a cost effective, easy to
assemble, mechanical joint for HDPE pipe conforming to ASTM F714,
D2447, D3000, or D3035 with wall thicknesses ranging from SDR 32.5 to
SDR 7.3. The Gruvlok coupling method also eliminates the need for costly
fusion equipment.
Each coupling uses four bolts to drive sharply machined teeth into the
outside of the HDPE pipe. When the teeth effectively grip into the pipe,
it provides a secure and rigid mechanical connection with pressure
capabilities exceeding that of the HDPE pipe itself. The banks of teeth are
positioned away from the gasket to enhance the gasket’s sealing ability
throughout the operating temperature range.
The Figure 7305 HDPE coupling also provides a low profile contoured
housing with ramps along the outside diameter. This allows the coupling
to slide over most obstacles when long lengths of the pipeline are relocated.
WARNING:
1. Gruvlok products for HDPE pipe must be installed using Gruvlok Xtreme™ Temperature Lubricant.
2. The listed gasket temperature rating may exceed the manufacturer’s temperature rating for HDPE pipe. Consult with the
HDPE pipe manufacturer for appropriate service temperatures before use.
3. The Figure 7305 HDPE Coupling is intended for use on HDPE Pipe only. Use of other plastic pipe materials is prohibited.
