Aqua Environment 708 708 Series SCBA Fill Adapter 4500 PSI

The model 708 fill adapter is designed to fill only 4500 PSI SCBA cylinders. If accidentally attached to the more common 2215 PSI cylinder a unique internal vent mechanism opens and prevents the cylinder from filling. Thus the danger of an inexperienced operator attaching a low pressure cylinder to a higher pressure line is eliminated.

Installation

Use a suitable pipe thread sealant. Do not over torque. Use average torque using a 6 or 8 inch wrench. Use ample Teflon tape - 3 or 4 turns not 1 or 2. Tightened by removing retainer clip item 5 and sliding the nut item 2 back to expose the wrench hex on the stem. Then slide the nut forward and, if desired, install the spring clip to keep the nut in the forward position. It is recommended a bleed or vent valve such as model 712 valve be used to vent line pressure after filling a cylinder. It is best to use the adapter at the end of a flexible high pressure hose. This eliminates unnecessary strain on the adapter and cylinder valve associated with rigid pipe connections.
