Description
This premium heavy duty HDPE welding rod in dark green is designed for reliable plastic repair, fabrication and lining work. Manufactured from high-density polyethylene, it delivers consistent melt flow and strong, durable welds on compatible HDPE components, sheets and extrusions.
Supplied in a convenient 2 kg coil of 4 mm round profile, this rod is ideal for workshop and on-site use in sectors such as tank building, pipework installation, aquaculture, environmental containment and general plastic fabrication.
Product Features
- Material: high-density polyethylene (HDPE) for strong, compatible welds on HDPE plastics.
- Profile: 4 mm round rod for versatile use with most hot air and extrusion welding equipment.
- Colour: dark green for colour-matched repairs and easy identification of weld lines.
- Coil format: supplied in 2 kg coils for efficient storage, handling and continuous welding.
- Consistent diameter and profile for even heat distribution and uniform bead formation.
- Suitable for both repair work and new fabrication in HDPE-based systems.
- Low moisture absorption to help minimise porosity and weld defects.
Key Features and Benefits
- Ensures strong, durable joints by matching the base HDPE material, improving bond integrity.
- 4 mm round profile offers good control over weld size and penetration, reducing rework.
- Dark green colour helps blend with coloured HDPE components for a neat, professional finish.
- 2 kg coil length reduces changeovers and downtime on longer welds and larger projects.
- Suitable for a wide range of plastic welding techniques, supporting versatile workshop use.
- Consistent manufacturing quality helps deliver reliable, repeatable welding performance.

Frequently Asked Questions
Is this HDPE welding rod suitable for all types of plastic?
No, this welding rod is formulated specifically for use with high-density polyethylene (HDPE). It should not be used on other plastics such as PVC, polypropylene or ABS, as this may result in weak or failed welds.
What welding equipment do I need to use this 4 mm round rod?
This rod can be used with suitable hot air plastic welders and extrusion welders that accept 4 mm round profile rod. Ensure that your equipment has appropriate nozzles and that you follow the manufacturer’s recommended temperature settings for HDPE.
Can I use this dark green rod for structural repairs on water tanks and pipework?
Yes, provided the base material is HDPE and correct welding procedures are followed, this rod is suitable for structural repairs on items such as HDPE water tanks, pipes and fittings. Always ensure surfaces are clean, properly prepared and welded by a competent operator for best results.
