Excellent quality slide valve to fit 43 mm solvent waste pipe,compact valve,suitable for filter waste and flow control.

This unique valve fits 40 mm (43mm) solvent waste on the inside and a 1.5" pressure fitting fits on to the outside saving even more space also useful if you were to glue a fitting in wrong ,being able to use the outside instead.

Photo shows how pressure fittings can be used on the outside (not included with the valve)
