Clear PVC 50mm ID Solvent Weld Fittings — See Your Flow, Seal It Right
When a hidden leak or blockage means tearing apart a finished installation, the real cost isn't the fitting — it's the labour. Plumbers, pool builders, and irrigation engineers who work with 50mm metric pressure lines need fittings they can inspect at a glance without cutting into the run. These clear PVC 50mm ID solvent weld fittings let you see flow, check for air locks, and confirm full solvent cure before backfilling or casing.
Each part is moulded from transparent rigid PVC rated for metric solvent weld assembly. The 50mm internal diameter (approximately 2 inches) matches standard metric pressure pipe. The range covers the full plumbing toolkit: Socket, 90° Elbow, 45° Elbow, Tee, Union, End Cap, Ball Valve, Double Union Ball Valve, Non-return Valve (Flap Type), a 50mm MBSP Socket Adaptor, plus consumables including 50mm Silicone Washers, PTFE Thread Seal Tape, and 33–57mm 304 stainless steel hose clamps.
Typical use cases include residential and commercial pool circulation lines where visual flow confirmation reduces call-backs, drip and spray irrigation manifolds where tee and elbow placement must be verified before burial, and light industrial process lines carrying water or compatible fluids where clear PVC solvent weld fittings allow non-invasive inspection.

Compatibility: Designed for 50mm ID (metric) clear or standard rigid PVC pressure pipe. Solvent weld joints require PVC solvent cement (not included). The MBSP Socket Adaptor connects to 1-1/2" male BSP threaded fittings. Verify pipe OD before ordering.

❓ Frequently Asked Questions
Which pipe does this fit — metric or imperial?
These fittings are sized for 50mm ID metric rigid PVC pressure pipe. The 50mm internal diameter corresponds to approximately 2 inches nominal, but metric and imperial pipe ODs differ slightly. Always confirm your pipe's outer diameter before ordering to ensure a solvent weld socket fit.
Can I use these fittings for pool or spa plumbing?
Yes. Rigid PVC is widely used in pool and spa circulation systems because it resists chlorinated water and common pool chemicals. The transparent body is particularly useful for pool builders who want to verify flow direction and check for air locks at the pump or filter without cutting into the line.
What solvent cement should I use?
Use a PVC solvent cement rated for pressure pipe applications. For clear PVC, a clear or light-bodied cement is recommended to maintain visibility through the fitting wall. Solvent cement is not included — select a product compatible with rigid PVC and your local plumbing code requirements.
How do I choose between the Ball Valve and the Double Union Ball Valve?
The standard Ball Valve is solvent welded in place and is best for permanent isolation points where removal is rarely needed. The Double Union Ball Valve can be unscrewed from both ends without cutting pipe, making it the right choice for equipment connections — such as pump inlets or filter ports — where periodic servicing or replacement is expected.
Is the Non-return Valve suitable for vertical installations?
The flap-type non-return valve relies on gravity and back-pressure to seat the flap. It performs reliably in horizontal runs and upward-flow vertical installations. For downward-flow vertical lines, confirm the flap closes fully under your system's static head before specifying this valve type.
What chemicals are these fittings resistant to?
Rigid PVC has good resistance to chlorinated water, dilute acids, alkalis, and many common irrigation fertilisers. It is not suitable for concentrated solvents, aromatic hydrocarbons, or ketones. If your application involves chemicals outside standard pool or irrigation service, consult a PVC chemical resistance chart before installation.
Can I mix clear PVC fittings with standard white or grey PVC pipe?
Yes, provided the pipe OD matches the fitting socket ID. Clear PVC solvent weld fittings bond to standard rigid PVC pipe of the same nominal size using the same solvent cement process. The joint strength is equivalent regardless of the pipe colour, as long as both components are rigid PVC (not CPVC or ABS).
