How to Connect & Disconnect the VEP-Series Coupling
1. Prior to connecting, thoroughly clean all mating surfaces and threads on both halves, then pull the coupler
sleeve forward.
2. To initiate the connection, align the coupler and plug, pushing/turning the coupler sleeve towards the plug while
engaging the threads. Keep the mating halves aligned during the connection process.
3. Allow the threads to pull the coupler onto the plug, do not push the coupler onto the plug.
4. The first phase of the connection should be threaded by hand, without the use of tools. Please note the connection
sleeve may seize when dirt and debris accumulate in the threads - wipe away debris with a cloth, compressed air,
or a brush.
5. The second phase of the connection may require a wrench if the pressure is higher than anticipated.
6. Continue to thread the coupler sleeve onto the plug until the end of the sleeve meets the plug body
7. To disconnect, use a wrench to break the coupler sleeve free and keep the mating halves aligned during the
disconnection process.
