- The Gruvlok® FIG 7001 coupling forms a flexible grooved end pipe joint connection with the versatility for a wide range of applications. Services include mechanical and plumbing, process piping, mining and oil field piping, and many others. The coupling design supplies optimum strength for working pressures to 1000 psi (69 bars) without excessive casting weight. The flexible design eases pipe and equipment installation while providing the designed-in benefit of reducing pipeline noise and vibration transmission without the addition of special components. To ease coupling handling and assembly and to assure consistent quality, sizes 1 in through 14 in couplings have two 180 deg segment housings, 16 in have three 120 deg segment housings, and 18 in through 24 in sizes have four 90 deg segment housings, while the 28 in OD and 30 in OD couplings have six 60 deg segment housings. The 28 in OD and 30 in OD are weld-ring couplings.
