- Check inside all components for any debris. If debris is present, use compressed air to remove.
- Install Connector - Apply thread sealer, then tightly thread the connector into the port hole of your machine using a 2.5-inch wrench.
- Install Sample Valve - Apply thread sealer, then tightly thread the sample valve with the pilot tube into the front port of the Hub body using one 1/16-inch wrench. IMPORTANT: Do not bend the Pilot Tube before you insert it into the Hub body. Be sure to remove the plastic blue caps on the threads and on the pilot tube tip.
- Bend Pilot Tube - Choose a bend location and angle which places the tip of the pilot tube within your machine for proper sampling. Before bending, identify the best orientation of the Hub body. Note that the Hub body has two 1-inch NPT lateral ports and two 3/4 inch NPT lateral ports. Also note that the Hub body can be installed in eight positions around the connector.
- Install Hub Body Onto Connector - Apply the supplied O-ring lubricant to the O-rings of the connector. Push the Hub body onto the connector so the connector is fully nested inside the Hub bod. Ensure that both O-rings are properly seated. Use the supplied bolts and 5/32-inch hex key to tighten the Hub body onto the connector.
- Seal Lateral Ports - Install compatible oil levels, glasses, BS&W bowls, quick, connects, etc. to the lateral ports. Be sure to follow manufacturers suggested instructions to ensure proper installation. Apply thread sealer to the supplied plugs and seal the remaining open lateral ports with the supplied 3/8-inch hex key.
- Final Step - Confirm that all threaded components are tight. Slowly replenish the machine with oil and check for leaks. Re-tighten and or reseal threaded components if any leaks occur.

- Pair the Hub with Column and Bowl to meet all of your lubrication inspection and sampling needs.
- Lateral ports may also be used to install quick connects for filter carts.
- Sample from the center valve on demand in accordance with your facility's sampling schedule.
- Sampling while the machinery runs is best practice.
- Ensure you have purged all of the non-circulating oil from the pilot tube before filling your sample bottle.
- For use with mineral and synthetic oils that are compatible with fluorocarbon elastomers (Viton), epoxy powder coated aluminum, stainless steel, and zinc-plated steel.
- Do not use cleaning solvents that are incompatible with fluorocarbon elastomers (Viton), epoxy powder coated aluminum, stainless steel, and zinc-plated steel.
- Install the Hub on machine port locations that are a safe distance away from moving machine parts and vehicles.

Intelligent Machine Health Management
#1. Sampling Valve
Convenient port to pull oil samples from the live zone
#2. Lateral ports
Great for use with the Bowl, Column, quick connects and more
#3. Shielded Design
Protects the sampling valve from impact
#4. 90° of rotation
Adjustable for proper orientation
3
Shielded Design
The shielded design of the Hub protects the sampling valve from impact and prevents particle build-up.
The 4 holes allow for easy access to install the screws into the thread reducer.
1
Sampling Valve
This is a convenient port that makes pulling samples from the live zone a breeze.
By using a sampling valve, you ensure consistency across your sampling program.
2
Lateral Ports
The hub features 4 lateral ports for any necessary attachments.
We suggest adding our Column and Bowl to monitor oil level and to provide contamination control.
The Lateral Ports may also be used for quick connects and other 3rd party accessories.
4
Adjustable Orientation
The Hub can be rotated every 90° for installation in your preferred orientation.
Luneta's patented connector allows for ease of installation with its forgiving tolerances.

Frequently Asked Questions
Where should I install the Hub?
The Hub should be installed at the drain port or anywhere below the oil level.
Is the 1/2" NPT Hub available in High Flow?
No. The high-flow pilot tube diameter is too large and will restrict flow into the Hub when using the ½” NPT connector.
What is the difference between High flow and Standard flow?
The high flow valve has a larger inside diameter which allows for greater sampling rates, typically three times that of the standard flow.
Can I use the same probe for the Pod and the Hub?
Yes, the standard flow Hub uses the same valve as the Pod, so the same probe can be used. However, the high-flow Hub uses a different probe that is incompatible with the Pod.
Still have questions?
