The Y99AY Series Manually Operated PIlot Adjust Adapter Fittings are used to change flame height to the pilot burner/device requiring lower BTU/hr.
The pilot flow rate can be adjusted from no flow to full flow by the use of a flat blade screw driver or small hex driver, by rotating the adjusting screw. BASO has four fittings available, all with male pipe inlet (MNPT threads) and outlets of 3/16 and 1/4 tube fitting connections.
Note: Compression nut and sleeve come with the fittings.
