20-200 RLB Permanenet Seal Bore Packer

Product Overview


The RLB is a high performance permanent seal bore packer designed for high pressure, high temperature applications. A large polished seal bore allows extreme flexibility and the largest possible ID through the packer and seal assembly and is an ideal choice for completions requiring mono-bore ID. The RLB is extremely simple and reliable and may be ran on wire line using the appropriate wire line setting tool and adapter or may be ran on tubing or drill pipe using a hydraulic setting tool and adapter. The RLB is available in 10,000 psi* differential pressure rated versions for most sizes and configurations. A full line of accessory equipment is available for the RLB packer such as seal assemblies, seal bore extensions, mill out extensions, tubing adapters, expansion joints, polished bore receptacles and disconnect devices. As standard the RLB is manufactured from materials which conform to NACE MR-01-75 for H2S service applications.  A wide variety of material and elastomer options is also available to suit virtually any well environment.
