Features
- Gruvlok Figure 7004 Coupling
- Designed to provide the versatility of a grooved joint while providing a connection for rigid pipe joint applications. This coupling permits working pressure ratings of up to 1000 psi (68.9 bar). Figure 7004 provides a basically rigid joint and does not allow for expansion or contraction. Available 2”-12” nominal pipe sizes
- Gruvlok Figure 7004 Coupling with EG® Gasket
- Uses the specially designed “END GUARD” gasket with “EG” grooved pipe. The “EG” gasket has a center rib that extends between the pipes to provide for pipe end protection, which makes it ideally suited for internally lined or coated pipe applications. Beveled end pipe should not be used with “EG” gaskets. Available 2”-12” nominal pipe sizes.
- Gruvlok Figure 7305 HDPE Coupling
- Designed for mechanically joined high density polyethylene pipe and fittings. The pipe is effectively gripped by two banks of at least two rows of spiral teeth, providing a secure mechanical joint with pressure capabilities exceeding that of the HDPE pipe itself. Available 2”-12” nominal pipe sizes.
- Gruvlok Figure 7307 HDPE Coupling
- Allows for transition from HDPE pipe or fittings to grooved end pipe prepared per Gruvlok standard cut or roll groove specifications for steel pipe or Gruvlok fittings.
- Gruvlok Figure 7401 RigidLokTM Coupling
- The Figure 7401 Rigidlok Coupling installation is fast and easy: remove only one nut and swing the housing over the gasket and into the groves. This coupling is an ideal connector for pumps, valves and fiberglass applications that require rigid connection. Available 1 ½” – 24” nominal pipe sizes.
- Gruvlok Figure 7000 Lightweight Flexible Coupling
- Designed for applications requiring moderate internal pressures. This coupling has a working pressure rating up to 600 psi (41.4 bar). The 7000 coupling is approximately 30% lighter in weight than the figure 7001 coupling. Superior performance in FRAC and cement applications. Available 1” through 8” nominal pipe sizes.
- Gruvlok Figure 7400 RigidLiteTM Coupling
- Specially designed to provide a rigid, locked-in pipe connection to meet the specific demands of rigid design steel pipe and copper tube systems. UL Listed and FM Approved for 300 psi (20.7 bar) fire protection service in both wet and dry systems with roll grooved or cut grooved steel pipe prepared in accordance with Gruvlok grooving specifications.
- Gruvlok Figure 7005 RoughneckTM Coupling
- Efficient and cost effective method of joioning either plain end or beveled end pipe. No pipe end preparation necessary. Available in 2” through 16” diameters.
- Gruvlok Figure 7003 HingeLokTM Coupling
- For applications requiring a Quick connection and/or disconnection of a pipe joint. The fig. 7003 Hingelok Coupling allows working pressure ratings up to 300 psi (20.7 bar). Available with Viton and silicone gaskets for more critical services. An optional heavey-duty locking pin can be furnished upon request. Available 1" through 8" nominal pipe sizes.
- Gruvlok Figure 7010 Reducing Coupling
- This figure coupling makes it possible to directly connect two different pipe sizes, eliminating the need for two couplings and a reduced fitting. The specially designed reducing coupling gasket with a center rib assures proper positioning of the gasket and prevents the smaller pipe from telescoping into the larger during assembly. Figure 7010 Reducing Coupling allows for working pressure ratings up to 500 psi (34.5 bar). Ranges 15" of Hg. vacuum to 300 psig on standard wall steel pipe. Available 2" through 8" nominal pipe sizes.
