Commonly referred to as a 50mm PVC well screen or slotted PVC screen, this product features precision cut 0.5mm slots with 4mm spacing to allow efficient groundwater flow while minimising sediment ingress. The smooth wall construction and consistent slot pattern support reliable groundwater sampling and monitoring well performance.

This 50mm PVC well screen is manufactured to Class 18 specifications and includes male and female threaded flush joint connections, allowing secure joining with compatible 50mm PVC monitoring well casing. The flush joint design maintains a smooth external diameter, supporting easier installation and accurate well construction.

Available in multiple lengths, measured shoulder to shoulder, which refers to the usable pipe length once the threaded ends are fully screwed together. This well screen allows flexible installation configurations to suit site specific investigation requirements and drilling conditions.

We also offer 1 metre lengths including the thread, which comply with airfreight transport requirements. This enables rapid delivery to remote locations and project sites across Australia, with urgent orders often delivered within just a few days.

This product is commonly used by environmental consultants, drilling contractors, geotechnical engineers, and groundwater specialists requiring dependable and compliant monitoring well construction materials.
