Pool Bulkhead Fitting 1/2" FNPT
The Hayward BFAS1005TFS is a 1/2-inch bulkhead tank fitting with female NPT threads on both sides. It suits pool and spa plumbing installations where a watertight pass-through is needed on curved or flat tank walls. The grey PVC body and FKM gasket resist common pool chemicals and provide reliable sealing for new construction or repair work.
Thermal And Pressure Performance
Rated for a maximum operating pressure of 150 psi at 70 degrees F, the fitting handles typical circulation pump pressures without leakage. It operates continuously between 40 and 140 degrees F, covering normal outdoor pool temperatures and heated spa loops. The PVC construction does not corrode, so thermal cycling does not degrade the seal or thread integrity over time.
Installation Fit And Clearance
Zero bolt holes mean the fitting installs by threading alone, simplifying cut-out preparation in the tank wall. Female threads on both faces accept standard 1/2-inch male pipe adapters, so no special unions or flanges are required. The straight-through design keeps the flow path clear and leaves full bore access for drain lines or suction fittings on either side of the wall.

Questions about this item
How do I install the 1/2" FNPT bulkhead fitting and what step is often missed?
Thread the fitting into the tank wall using the female NPT connections on both sides; the step often missed is ensuring the FKM gasket seats evenly against curved or flat surfaces before tightening to prevent leaks at 150 psi.
What maintenance will the BFAS1005TFS trap need over time?
Inspect the FKM gasket periodically for hardening or chemical attack, especially after exposure near the 140 °F maximum temperature, and replace it if sealing performance drops.
What limit appears first when the fitting runs continuously under pressure?
The 150 psi rating at 70 °F is the primary limit; sustained pressure above this value or temperatures approaching 140 °F will reduce the allowable pressure further.
