Designed to be bolted to the outside, or inside, of large diameter PE pipes. This is a cost effective alternative to other models where speed of installation / removal is less critical. Available in the size range 400mm to 1200mm. The Bolt-On Towing Head has been designed as a cost effective solution to the problem of obtaining a strong and reliable pulling attachment onto larger (400mm +) PE pipes of any wall thickness (SDR). It is available as a sealed, or unsealed unit making it suitable for both Directional Drilling and Slip Lining applications as well as a method of pulling PE pipes during direct burial installations. On the sealed variant the Towing Head is supplied already attached to a metre length of capped PE pipe. The unsealed variant is usually supplied as a bare unit suitable for fitting on site to a pipe section. For applications where it is not desirable to increase the outside diameter of the pipe by even a small amount, i.e. tight fit slip lining, the Bolt-On Towing Head can be manufactured to fit inside the PE pipe and therefore not increase the outside diameter at all. Please contact us for prices and information.

Pipe Cutter Features
- Cuts Ductile Iron & Steel pipes & other materials
- Suitable for all pipes 40mm (1 1/2") upwards
- Can cut slots of up to 600mm long and 20mm deep
- Accuracy of cut with digital depth gauge
- Fast - 30 minutes to cut a complete window
- Reduces the risk of ‘white finger’

LINK SEALS are used to provide a seal between a product pipe or cable and a casing sleeve, duct or wall. LINK SEALS provide a modular hydrostatic sealing mechanism that is independent of internal or external pressure, and can provide a pressure seal up to 5 bar. LINK SEALS also provide electrical and vibrational insulation, and can provide fire resistance for up to three hours. The rubber material absorbs shocks and sounds, and reduces the vibration load on the pipes and cables. The unique link structure makes it possible to produce an almost unlimited number of sizes. Please download the data sheet to show different options available. Our sales team can advise suitable Link Seal and core hole sizes upon request. The seal is supplied in an assembled condition with the required number of links, and owing to its special design the LINK SEAL chain is rapidly installed.
