SDR 9 PN20 90° Spigot Elbow PE100 Butt Fusion Elbow for Water Supply ISO 4427

90° Spigot Elbow PE100 SDR 9 — ISO 4427 Moulded Butt Fusion Fitting, PN20

The PE100 90° spigot elbow (SDR 9) is a high-pressure moulded fitting with plain pipe-end (spigot) connections on both sides, engineered for butt fusion jointing directly to PE100 pipe of the same SDR. Rated Water PN20 (2.0 MPa at 20°C), SDR 9 occupies the mid-high pressure band of the PE100 programme — between the PN25 heavy-wall class (SDR 7.4) and the PN16 standard class (SDR 11) — making it a versatile choice for demanding water networks.

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

The range covers d20mm to d500mm, with d20-315mm held as standard stock and larger sizes produced on request. Each fitting is individually marked with size, SDR, standard and batch codes.

Typical Applications

• High-pressure water supply and distribution networks (PN20)
• Irrigation mainlines and booster stations
• Industrial process water and cooling water lines
• Municipal water works and pump station headers
• Butt fusion PE100 systems where electrofusion is not available

Key Features & Benefits

• SDR 9 / PN20 rating — 2.0 MPa high-pressure class, ideal for demanding networks
• ISO 4427-3 certified — full compliance with international water piping standards
• Moulded one-piece construction — smooth bore, no seams, lower pressure loss
• Butt fusion jointing — 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 on site
• Virgin PE100 material — Borealis / Ineos polymer, full batch traceability
• Wide range d20-500mm — one source for the full network programme

Why Choose SDR 9 for Your Network?

SDR 9 gives you high-pressure capability with a lighter wall than SDR 7.4, balancing strength and material economy. It pairs with SDR 9 PE100 pipe for full-strength butt fusion joints, and is the standard choice for PN20 water supply schemes across municipal, agricultural and industrial projects.

Dimensions — Moulded 90° Long Spigot Elbow, SDR 9 (PN20)
