Harness Makes Backpack Sprayers Easier to Pack and Less Likely to Leak

Rubber Pipe Plug Diagram Long Description

Drawing of a rubber pipe plug.

Drawing of a rubber pipe plug. In the drawing the text reads, Air Flow Direction, See Note NO. 3, and Tank.

Under the Material List the text reads, Plug, Check Valve, Fitting, and Tubing along with the descriptions of each material.

In the Notes section the text reads:

  1. Other plug sizes are available make sure plug size ordered fits tank opening.
  2. Inside of tank opening should be smooth. Some tank openings such as on Solo backpack sprayers have small ribs or protrusions inside tank opening which must be filed or ground down.
  3. The top of the plug (part No. 1) must be drilled and tapped for (part No. 3) drills size 37/64, tap size 3/8-18 tapered.
  4. Over tightening plug (part No. 1) in tank opening could split the tank.
  5. Additional vinyl tubing (part No. 4) can be attached to the check valve (part No. 2) to divert leakage away from the operator or equipment.
  6. Flush the check valve with clean water when rinsing the tank.
  7. Install check valve so that air flows into the tank and keeps liquid from escaping.
