At PetroMarys, LineBacker® provides reliable flange isolation, electrical insulation, and corrosion protection for oil, gas, water, and chemical pipelines. Designed for ANSI, API, and AWWA flanges, these gaskets and kits ensure zero leakage, low bolt stress, and long-term durability.

• Full-face (Type E) or ring-type (Type F) gaskets for all flange types

• Pressure-energized quad-ring seals for tight, self-aligning installation

• Sleeves and washers for maximum electrical isolation and safety

• Strainer versions protect downstream valves, pumps, and compressors from debris

• NSF 61-certified kits for potable water applications

• High-resistance materials (G10/G11 GRE, PTFE, EPDM) for vibration, thermal cycling, and MIC

Benefits: Easy installation, reusable, reduces flange erosion, prevents galvanic corrosion, filters debris, handles high pressures, and maintains electrical isolation.
