Brass Male Adaptor 20mm

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.

6. SUREFIT HELIX - Patented design feature prevents pipe from falling off, ensures precise positioning.

7. SEALING RIBS - Narrow lands with wide grooves ensure clamp stress is transferred into the pipe joint efficiently.
