The WE6-LL M10x1K is a 90-degree elbow connector from the LL light series for 6 mm lubrication lines. Its M10 x 1.0 metric fine male thread screws into a matching port, while the compression side grips a 6 mm tube and turns the line through a right angle. Use it where the routing space is too tight for a pre-bent tube run.

Configuration and Placement
This elbow solves a routing problem, not a flow problem. Where a lubrication line has to turn a right angle at a port, inside a machine frame, behind a guard, or at a pump outlet, a straight fitting would force a tight bend into the tube. Pre-bent tube is one alternative, but a fixed 90-degree elbow keeps the bend consistent and holds the tube end square to the fitting. Because the elbow cannot be rotated once tightened, set the outlet direction first and then torque the thread home with an 11 mm wrench.
Materials and Media
The standard body is zinc-plated steel. For lines that run in wet or corrosive areas, SS316L and nickel-plated brass versions are available. The fitting is intended for mineral oil, synthetic lubricating grease, and biodegradable fluids. Confirm the thread form and sealing arrangement when ordering.
Tubing and Related Fittings
The compression end works with common 6 mm nylon and polyurethane tubing, including the 6 mm PA12 lubrication tube. If the line continues straight out of a port instead of turning, use a fitting from the compression straight tube fitting family. For layouts built around push-to-connect rather than compression connections, see the push-to-connect grease line fittings.
What Is Supplied
Each order of this part covers the WE6-LL M10x1K elbow connector as described above: an M10 x 1.0 male thread on one side and a 6 mm compression connection on the other, in zinc-plated steel as standard. The SS316L and nickel-plated brass material options are supplied on request, so state the option you need when ordering.
Honest Limitations
- Fixed angle: the elbow cannot be rotated after installation. The outlet direction must be chosen before final tightening.
- Light-series rating: the LL series suits systems within the 0 – 100 bar working range. It is not sized for circuits whose peaks could exceed the 250 bar maximum pressure.
- Thread match required: the M10 x 1.0 fine thread only fits ports of the same thread. An M10 x 1.5 port needs a different fitting.
If you want help matching thread, tube, and material to your line, request a quote for the WE6-LL with your port thread and tube details.
Frequently Asked Questions
Is the WE6-LL M10 x 1 elbow the right fitting for my line?
Choose it when a 6 mm lubrication line must turn a right angle at an M10 x 1 port and space is too tight for a bent tube. If the line continues straight from the port, a straight compression fitting is the better match; if you need quick disconnection, look at push-to-connect styles instead.
What does the LL series designation mean?
LL is the light series in this connector family. It covers compact fittings for smaller tube sizes and a working pressure class up to 100 bar, which suits most centralized lubrication lines.
How is M10 x 1 different from M10 x 1.5?
Both threads have a 10 mm major diameter, but the pitch differs: 1.0 mm is the fine pitch and 1.5 mm is the coarse pitch. They are not interchangeable, so measure the port thread before ordering.
Does 6 mm refer to the tube outside diameter?
Yes. The 6 mm rating refers to the outside diameter of the tube that the compression end grips.
What pressure can the WE6-LL handle?
The working pressure range is 0 – 100 bar (1,450 PSI), with a maximum pressure of 250 bar (3,625 PSI). Check the fitting rating against the peak pressure your system can actually see, not just its normal running pressure.
How tight should the WE6-LL be installed?
Tighten the thread to 25 – 30 Nm using an 11 mm wrench on the hex, which measures 11 mm across flats.
How should the M10 x 1 thread be sealed?
Confirm the thread form and sealing arrangement when ordering, and follow the port manufacturer’s requirement for your specific connection.
Can the elbow be rotated after installation?
No. Once tightened, the elbow holds a fixed direction. Set the outlet angle first, then tighten to the specified torque.
Which straight fittings and tubing pair with this elbow?
On the same 6 mm line you can combine it with fittings from the compression straight tube fitting family and run it on 6 mm PA12 tube or common polyurethane tubing.
