Topaz offers a large and comprehensive line of bolt-on style pipe fittings for both low and high pressure service. Mechanical leak repair sleeves for pipe, tees, ells, flanges, and valves are stocked in standard configurations, or can be custom designed for unique applications. We also offer mechanical flanges, tapping tees, line plugging tees, and couplings for construction of new, or the revamp of existing piping systems in areas where welding is not feasible. With elastomeric seals chosen for product compatibility, these high pressure fittings perform at full rating as a mechanical repair or connection in both onshore and subsea installations.
