Product Description
The Primepoly PVC coupling joins two equal-diameter pipes end-to-end with a centre-stopped solvent-weld socket on each side. The most-used fitting in any PVC system — for repairs, length extensions and manifold assembly — moulded to ASTM D2466 / ISO 1452-3 dimensions for 100 % interchange with the leading global brands.
Advantages and Characteristics
1. Centre-stopped sockets ensure even, full-depth insertion on both pipes.
2. Smooth internal bore matches pipe ID — no flow restriction or turbulence at the joint.
3. Solvent-weld socket × socket plus repair-coupling versions (no centre stop) for in-line repairs.
4. DN20 – DN500, PN10 / PN16, 0–60 °C continuous duty.
5. Lead-free PVC-U; NSF/ANSI 61 certified on request.
Typical Applications
Used everywhere two pipes meet: extending runs that exceed factory pipe length, repairing damaged sections, joining pipe lengths during manifold pre-fabrication, and connecting to factory-bevelled pipe ends. The repair-coupling variant slides over an existing pipe with no centre stop, allowing two cuts and one slide-on insertion for in-place fixes.
Quality and Compliance
Every Primepoly PVC coupling is moulded from food-grade, lead-free PVC-U compound and tested to ASTM D2466 (Sch 40), ASTM D2467 (Sch 80), ISO 1452-3 and EN 1452-3. Optional NSF/ANSI 61 certification is available for potable-water service. Pressure ratings PN10 / PN16, working temperature 0–60 °C, service life over 50 years when installed per manufacturer guidelines.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for HDPE / PVC pipe?
Standard MOQ varies by product — generally 1 ton for HDPE pipe, 500 kg for PVC pipe, and one full container for export orders. Custom MOQ is available for sample / pilot projects — contact our sales team for confirmation.
What is the typical lead time?
For stocked sizes, 7–10 days from order confirmation; for custom OD / SDR / colour, 25–35 days. Production capacity exceeds 2,000 t/month — large project orders are scheduled in batches.
Which certifications does Primepoly hold?
ISO 9001, ISO 4427, AS/NZS 4130, ASTM F714, AWWA C906, WRAS and NSF 61. Documentation accompanies every shipment, and third-party inspection (SGS / BV) is welcome at the buyer's request.
Do you offer OEM and private-label manufacturing?
Yes — we manufacture pipes and fittings to customer-specified OD, SDR, length, colour, marking and packaging. MOQ for OEM orders typically starts at 5 tons or one full container.
How are pipes packaged for export shipping?
Pipes are bundled with PE film / steel strap and stowed by length: short pipes (≤6 m) ship in 20'/40' containers; long pipes (>12 m) ship by break-bulk vessel or flat rack. Coil rolls are shrink-wrapped and palletised. Free OBL with shipping documents.
