  • High-pressure rating handles 335 psi for demanding hydraulic systems

  • 50-pack supply reduces reorder frequency for maintenance teams
  • Metric M8X1 thread fits 4 mm tubes without adapters

Pack Contents

This Legris pack supplies 50 brass compression nuts built for 4 mm metric tubing. Each nut carries an M8×1 thread and an 11 mm overall length, making it a direct-fit hardware item for maintenance teams and OEM assemblers working on pneumatic or hydraulic circuits.

Upgrade Context

The nuts replace worn or corroded originals on existing Parker-series brass metric compression fittings. Swapping them out is worthwhile when a joint shows leakage, thread damage or when a system is being re-certified to ATEX, PED, REACH, RoHS or WEEE standards.

Installation Notes

Installation is a simple hand-tighten plus a spanner turn; no special tools or sealants are required because the ferrule already on the tube does the sealing. The most common mistake is over-torquing, which distorts the C36000 brass threads and can crack the ferrule, so stop at the manufacturer’s recommended torque value.

Questions about this item

What tube size fits the 4 mm Legris brass compression nut?

The nut is designed for tubing with a 4 mm outer diameter and uses an M8×1 thread to secure the connection.

How do you install the nut without damaging the 11 mm brass body?

Slide the nut onto the tube, insert the tube fully into the fitting body, then tighten by hand plus one spanner turn; over-tightening strips the C36000 brass threads.

When should the brass nuts be replaced in a 100 °C hydraulic system?

Replace nuts if threads show galling, the compression face is deformed, or after the system exceeds the 3,335 psi pressure rating during service.
