90 Degree Spigot Elbow PE100 SDR 7.4 PN25 High Pressure Butt Fusion Elbow for Water Supply

The PE100 90° spigot elbow (SDR 7.4) is a heavy-wall moulded fitting with plain pipe-end (spigot) connections on both sides, engineered for butt fusion jointing directly to PE100 pipe of the same SDR. SDR 7.4 is the thickest standard wall class offered for PE100 fittings, giving a Water PN25 pressure rating — ideal for high-pressure water supply, mining process lines and high-rise building pipework.

Manufactured from virgin PE100 black polyethylene supplied by recognised polymer leaders such as Borealis and Ineos, our spigot elbows carry full batch traceability. The moulded construction produces a smooth bore with no seams, maximising flow and eliminating stress concentration points. Long spigot ends give the welder generous space for clamping and fusion, while factory-chamfered ends follow DVS 2207 / ISO 21307 welding procedures.

Available as a standard stock range from d25mm to d315mm, with sizes up to d500mm available on request. Each fitting is individually marked with size, SDR, standard and batch codes.

• High-pressure water supply and distribution networks (PN25)
• Mining and process water lines requiring heavy wall sections
• High-rise building plumbing and riser pipework
• Irrigation booster lines and pump station headers
• Butt fusion PE100 pipeline systems where electrofusion is not available

• Heavy-wall SDR 7.4 — thickest standard PE100 fitting wall class, PN25 water rating
• Moulded one-piece construction — smooth bore, no weld seams, lower pressure loss
• Butt fusion jointing — strong full-strength PE-to-PE weld per DVS 2207 / ISO 21307
• Long spigot ends — generous clamp and weld area for the fusion machine
• Factory-chamfered ends — ready for immediate butt fusion, reduces site prep time
• Virgin PE100 material — Borealis / Ineos polymer, full batch traceability
• Certified standards compliance — EN 12201-3, ISO 4427-3, EN 1555-3
• Individual barcode / batch marking for quality control

Spigot (butt fusion) fittings allow high-performance pipeline systems with a more diverse range of fittings than electrofusion, especially for larger diameters and heavy-wall high-pressure classes. Butt fusion welds achieve 100% of the pipe's tensile strength, making SDR 7.4 spigot elbows the standard choice for PN25 water systems.

Note: Z = centre-to-end dimension, L = total length over spigot ends. Dimensions follow ISO 8085-3 series conventions for moulded long spigot elbows (typical values, ± tolerance per standard). Sizes above d315 up to d500 available on request. Contact us for CAD drawings.

All spigot fittings are manufactured from certified PE100 virgin material and tested against international piping system standards. Production is backed by ISO 9001 and ISO 29001 quality management systems.
