Lincoln 223-10080-5 Straight Fitting
This page identifies the Lincoln 223-10080-5 as a straight screw-in fitting that adapts a 10 mm tube to a 1/4 NPT port. The body is steel, and the part is listed as an aftermarket cross-reference item. See how a central lubrication system uses such fittings before ordering.
This page exists so maintenance teams can compare the Lincoln designation with a physical fitting before purchase. It does not replace the official catalog, but it records the verified attributes shown above.
Verified Identification
- Tube connection: 10 mm tube
- Port thread: 1/4 NPT
- Material: steel
- Series context: The 223 series appears in SKF Lincoln fittings and accessories documentation; related 223-10080-3 appears in an official cross-reference list, while the -5 version appears in distributor listings described as a longer-body configuration.
Catalog context shows this part only in distributor pages, not in the retrieved official material with a decoded suffix. The available official list covers the 223 series family but does not decode the -5 final digit. The distributor listings that mention -5 do not attach an official engineering note to the final digit. Cross-reference identification therefore relies on the 10 mm tube and 1/4 NPT thread values.
What the Suffix Does and Does Not Tell You
The final digit (-5) is not decoded in the retrieved official material. A longer-body description for the -5 version appears solely in distributor listings, not in an SKF publication. Request the current catalog sheet at quotation to confirm the exact body profile. Treat any claim about the -5 body length as a listing observation, not as a specification from Lincoln. The safest path is to request the current sheet before a first order.
What a Screw-In Tube Fitting Does
A screw-in tube fitting grips the tube end and seals the threaded port so flow carries straight through. It does not meter anything; metering happens only in metering devices placed elsewhere on the lubrication line. For a related adapter option, see this Lincoln adapter for lubrication systems.
The fitting body does not contain a valve or a restriction. Flow volume and timing at each lubrication point are controlled by separate metering devices.
Where It Fits
This fitting mounts on a lubrication distribution line where a 10 mm tube must enter a 1/4 NPT port. It is placed between the tube end and the threaded component body to create a straight path. For another port transition part, check this quick plug elbow fitting.
Installation follows the usual screw-in practice: thread the port side in, then secure the tube end with the retention method specified for the 10 mm line. Because the fitting is straight, the line does not turn at the connection point.
Ordering Practice
Confirm the tube size is 10 mm and the port thread is 1/4 NPT before ordering. Check that the port is 1/4 NPT, not BSPP or metric, since thread forms are not interchangeable. Order spares with the same part number to keep the assembly unchanged. contact the quotation team for help with identification.
If the existing fitting has a damaged thread or a rounded hex, replace it with the same number rather than mixing a different series. A dimensional check against the catalog sheet helps avoid returns caused by thread-form mismatch.
Frequently Asked Questions
Is this fitting a metering device?
No, it only adapts a tube to a port. Metering happens in separate metering devices on the line.
What thread does the port side use?
The port side uses 1/4 NPT. That thread must match the receiving component exactly.
What tube size does this fitting accept?
It accepts a 10 mm tube end. The tube is pushed or retained by the fitting body once installed.
Is the -5 suffix officially decoded?
No, the retrieved official material does not decode the -5 final digit. Distributor listings describe it as a longer body, but that is not from SKF.
Can this fitting be used with a metric port?
No, it uses a 1/4 NPT port thread. A metric port would not seal correctly on this fitting.
What material is the body made of?
The body material is steel. This matches the general 223 series construction.
Does this fitting include a metering orifice?
No, it has no metering orifice. It only carries flow straight through from tube to port.
How is the -5 version different from 223-10080-3?
Distributor listings describe the -5 as a longer-body configuration. The official cross-reference list shows 223-10080-3 but does not compare body lengths.
Should I confirm the catalog sheet before installing?
Yes, request the current catalog sheet at quotation to verify the body profile. That step avoids confusion about the -5 suffix description.
