Buteline fittings are integrally strong and durable, moulded from a high tensile premium grade custom thermoplastic and pre-fitted with annealed aluminium sleeves.
These one-piece plumbing fittings, once jointed with Buteline Polybutene-1 pipe, form a unique and technically superior joint that is maintenance free. Users will find Buteline fittings much quicker to install and more economical than other available systems.
1.8mm WIDE FORGED CLAMP - Minimum working stress applied (approx. 0.5 ton per sq. in.) allowing pipe material to “flow” into insert tail grooves.
2.2mm WIDE FLARE - No stress from clamping transmitted to insert tail or pipe at end of fitting. End of metal sleeve cannot impinge into pipe, even in bending.
3.TAPERED ENTRY, SMOOTH BORE - Minimises resistance to water flow.
4.METAL REINFORCING SLEEVE - Guarantees no stress break in this critical area.
5.FULL LENGTH ALUMINIUM SUPPORT - Provides additional rigidity and resistance to pull-off. Seals against dirt and moisture.
