Poolskim Union Insert Fitting - 40mm

The 40mm union insert fitting is a rigid, grey plastic adaptor designed to connect a PoolSkim unit to your pool’s return plumbing. The top section features a square, grip-friendly collar that helps with installation, while the lower body includes a knurled ring for a secure, hands-on engagement. A black threaded tail completes the stack, ready to mate with compatible pool fittings.

Engineered for reliable, water-tight performance in standard pool piping, this union-style adaptor offers a straightforward, tool-free grip and a solid, leak-conscious connection point between components. The compact, cylindrical form keeps installation tidy and minimizes protrusion into the plumbing line.
