12" Bayonet Inflator Gauge Hose Whip Replacement Milton’s S-527 is the replacement hose whip for the Milton bayonet inflator gauge #522. With ¼” NPT threads, this 12” bayonet inflator gauge hose whip is compatible for use and connection with any of the 4 Milton Bayonet Inflator bodies: #520, #521, #522, and #523. Offers 10-120 PSI or 80-840 kPa. The air chuck has 1/8”-27 NPT threads. This hose whip is free-flowing and cannot be used without the Bayonet Inflator Gauge- Air is turned on/off by the bayonet controller. If connected directly to an air source, air will constantly flow out. Other replacement parts: S-527 replacement air chuck: Milton #500-4. INSTRUCTIONS FOR USE: If using a dual head type tire chuck with an inflator gauge and notice air is escaping through the off-side once connected to the tire’s Schrader valve, simply release the trigger and remove the inflator from the Schrader/tire valve. Point the straight side of the outlet up into the air (make sure it’s not pointed at someone). Squeeze trigger, allow air to flow (gravity will cause the sealing valve to drop), and place the chuck end onto the Schrader/tire valve while air is still flowing. Air will start to flow into the tire. Dual head type tire chucks are unable to inflate a completely flat (zero air pressure) tire. Tire air pressure would normally cause the sealing valve to move and seal the unused side of the chuck. However, if a tire has 0 air pressure, the self-sealing valve has no pressure to react to.
