Aftermarket 112-35127-2 Pressure Plastic Tube
This page describes an aftermarket pressure plastic tube that cross-references the Lincoln 112-35127-2. Lincoln is a trademark of its respective owner. This is an aftermarket tube, not manufactured, sponsored, or endorsed by Lincoln. 112-35127-2 designations are for cross-reference identification only. The tube is made from PA12 polyamide for grease and oil conveyance in centralized lubrication systems. It is black, supplied unfilled, and available in coils up to 50 m.
Construction
The tube is constructed from PA12 polyamide with a 6 mm OD x 3 mm ID and a 1.5 mm wall. Precision dimensional tolerances provide reliable fitting retention across push-in connections. Low moisture absorption helps prevent dimensional change during service. The black color provides weather resistance for exposed routing. Weight is 45 grams per meter.
Working Pressure and Temperature Derating
The working pressure is 89 bar at 23 C. Pressure derates as temperature rises. Always check the derating table against your hottest point, not just the nominal 89 bar. The temperature range is -40 to +120 C.
| 23 C | 89 bar |
| 40 C | 75 bar |
| 60 C | 62 bar |
| 80 C | 50 bar |
| 100 C | 40 bar |
| 120 C | 30 bar |
Routing and Installation
The minimum bend radius is 50 mm. Tighter bends kink the tube and reduce pressure life. Cut the tube square and free of scratches for push-in fittings. Fully insert the tube into each fitting. Protect the tube from abrasion and hot surfaces. Coils are available up to 50 m.
Plan the route with support clips at regular intervals so the tube does not sag or vibrate against machine edges. Where the tube passes through a panel, fit a grommet so the metal edge cannot score the wall over time. Keep the tube away from chips, coolant spray, and hot surfaces wherever possible, and recheck the whole run after the first weeks of operation for any rub marks that appear.
Chemical Compatibility
This PA12 tube is compatible with mineral oils, synthetic lubricants, lithium based greases, and calcium based greases. Confirm additives with your lubricant supplier before installation. For system layout guidance, see progressive lubrication systems.
What to Confirm Before Ordering
Confirm 6 mm OD matches your fittings, because push-in fittings grip the OD. Confirm working pressure at your actual temperature from the derating table. Confirm chemical compatibility with your lubricant. Confirm coil length needed up to 50 m. For pump interface details, see grease pump. If you need help with selection, contact the team.
Frequently Asked Questions
What is the pressure rating of this tube?
The working pressure is 89 bar at 23 C. That pressure derates as temperature rises.
Can I use 89 bar at any temperature?
No, pressure derates as temperature rises. Check the derating table at your hottest point.
What size is this tube?
The tube is 6 mm OD x 3 mm ID. The wall thickness is 1.5 mm.
What is the minimum bend radius?
The minimum bend radius is 50 mm. Tighter bends can kink the tube.
What length can I order?
The tube is supplied in coils up to 50 m. Confirm the length needed for your run.
What fluids can this tube carry?
It handles mineral oils, synthetic lubricants, lithium based greases, and calcium based greases. Confirm additives with your supplier.
Will it fit my push-in fittings?
Confirm the 6 mm OD matches your fittings. Cut the tube square and scratch free.
What is the temperature range?
The tube operates from -40 to +120 C. Working pressure derates across that range.
