On the GEO 612 what size is the thread on the barbed fittings for feed line and effluent output? Is it 3/8" NPT or 1/4"? Want to change the barbed fittings out for mur-lok 1/4" push connects.
Hello, the GEO CR612 feed line female thread is a 1/8" NPT. The GEO CR612 effluent female thread is also 1/8" NPT. Thank you for your support of the GEO Calcium Reactor Line.
