Aqua Environment 835 835 Series SCBA Fill Adapter 4500 or 2215 PSI

The model 835 fill adapter is a straight adapter without the relief feature. It can be used to fill either the 4500 or 2215 PSI cylinders thus is normally used only on the lower pressure fill line. In facilities where both high and lower pressure fill lines are provided the 835 adapters can provide a matched set. The 835 is gold anodized and slightly shorter. Both adapters use a unique O ring sealed tip. Light finger tightening assures a good seal.

Typical Applications:

• Cylinder charging stations
• Mobile and stationary fire fighting facilities
• Connection to, filling, and transferring from CGA cylinders

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. The fitting is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.
