Brewis fuse on towing heads are machined from solid polyethylene for high strength. They range in size from 63mm to 740mm. The fuse on heads have sealed high tensile drop forged eyebolts for superior attachment and a stepped design at the back for easy butt fusion to either SDR9, SDR11 or 17.6 pipe. (Other SDR's can be made to order.)

The range of “BIG RIG” swivels are a further development of the famous Brewis Heavy Duty Swivel. Brewis manufacture a multitude of sizes from 44 to 550 US tons in box to clevis or clevis to clevis design. Each swivel uses an SKF Explorer or FAG X-Life spherical roller thrust bearing of a declared size. i.e. The 154 US Ton swivel contains a bearing with a dynamic capacity of 154 US Tons. Most swivel makers don’t declare the bearing capacity of their swivels but instead quote a figure for the strength of the supporting steelwork; this isn’t much help if the bearing has seized!
