Key Features & Benefits
- Stackload stackable design — fittings nest safely together, cutting warehouse storage space and transport costs
- Covers the widest main range: DN63 to DN355mm with 20-32mm service outlets (39 combinations)
- Manufactured using virgin PE100 black polyethylene for long-term durability
- Water PN16 / Gas 10 Bar rating (dependent on PE pipe welded)
- Live or dead main connection — no need to shut down the pipeline
- Tamper-proof LockCap — cannot be over-tightened, won't vibrate loose
- Two O-ring seals protect against leakage at the clamp interface
- Optional cutter tube locks into the integral cutter for leak-free cut-through of the main pipe
- Double spigot outlet — sufficient spigot length to cut off the coupler and fuse a second fitting
- Optimised saddle and fusion mat minimize joint cycle times
- 4mm automatic pin — auto-detects welding parameters, prevents operator error
- SDR range 11–17.6 (11–21 for DN250-355), covering common PE pipe wall thicknesses
- Rising pin fusion indicators allow easy visual monitoring of the fusion process
- Welding parameters moulded directly into the fitting body
- Individually numbered for precise batch tracking and quality control
- Permanent batch number clearly marked for traceability
- Barcode and QR code enables full traceability back to raw materials
- Welding barcode compliant with ISO 13950; traceability barcode compliant with ISO 12176-4
- Fully welded joint — no gaskets, no flanges, no future maintenance

Note: Regional variations may apply. Other product certificates available upon request.
Shipping & Delivery Information
We export PE electrofusion tapping saddles worldwide. Small sizes are packed in cartons on pallets; larger sizes are individually polybagged and crated for safe sea freight. The stackable design also reduces freight volume for bulk orders.
After-Sales Service & Warranty
We stand behind the quality of our electrofusion fittings. Our commitment doesn't end at delivery — we provide comprehensive technical support for your PE pipeline project.
Frequently Asked Questions
Common questions about our Stackload tapping saddle
What does 'Stackload' mean in this tapping saddle?+
Stackload refers to the saddle's stackable design — fittings are shaped to nest safely on top of each other, cutting warehouse storage space and transport costs for bulk orders.
What main pipe sizes does this tapping saddle cover?+
The Stackload tapping saddle covers mains from 63mm to 355mm with 20mm, 25mm and 32mm service outlets — 39 combinations in total from 63×20 to 355×32.
Can it be installed on a live main without shutting down?+
Yes. The saddle provides a direct connection from a live or dead main. An optional cutter tube locks into the integral cutter allowing a leak-free cut-through of the mains pipe without interrupting flow.
What pressure ratings are supported?+
Water PN16 and gas 10 bar, depending on the PE pipe welded to and local pipeline pressure regulations. For UK gas applications: 5.5 bar Class B / 7 bar Class C, size and outlet dependent.
What is the minimum order quantity?+
The standard MOQ is 100 pieces per size, but we are flexible for trial orders. Smaller sample quantities are available for evaluation. Contact us with your required sizes and quantity for a tailored quote.
