  • 3,335 psi pressure rating handles demanding fluid systems

  • 4 mm metric sleeve fits Parflex Braa compression fittings
  • 50-piece pack provides enough sleeves for multiple installations

Legris 4 mm Brass Compression Sleeve

This pack contains 50 metric compression sleeves made from C36000 brass for 4 mm outer-diameter tubing. The sleeves suit pneumatic and hydraulic circuits in automotive and industrial plumbing systems. They are compatible with Parflex compression fittings and accept brass, copper, polymer or steel tube. The fittings carry ATEX, PED, REACH and RoHS/WEEE certifications.

Sustained pressure and temperature limits

Each sleeve is rated to 3,335 psi maximum operating pressure and 100 °C maximum operating temperature for continuous service. Brass construction resists corrosion in typical fluid-power media without degrading under prolonged thermal cycling. The C36000 alloy maintains dimensional stability so seal integrity does not relax over long runs. California Proposition 65 warnings apply for listed chemicals.

Installation notes and common issues

Slide the sleeve onto clean, square-cut tube before inserting into the compression body and nut. Over-tightening the nut can crush the sleeve and create a leak path. Re-using a compressed sleeve is not reliable because the brass work-hardens and will not re-seal. Verify tube outer diameter is exactly 4 mm; undersize or oversize tube prevents proper ferrule bite.

Questions about this item

Does the brass sleeve handle continuous operation at 100 Degrees C without degrading?

The sleeve is rated for a maximum operating temperature of 100 Degrees C and a maximum operating pressure of 3,335 psi, so it is designed to withstand sustained heat and pressure within those limits.

What tube size and material are required for this 4mm compression sleeve to seal properly?

It fits 4mm outer-diameter tube made of brass, copper, polymer or steel and is intended for use with Parflex metric compression fittings.

Will these sleeves work with my existing Parflex metric compression fittings?

Yes, the sleeves are listed as compatible with Parflex brand fittings and conform to the Braa metric compression series, so they match the same connection type.
