Legris 0106 04 00 4mm Brass Compression Union 10PK

SKU CH-SH7Z-67RKF

Pack of ten brass compression unions joining 4 mm tube with 28 mm overall length, rated to 335 psi and 250 °F

  • Connects 4 mm tubes with compression fittings
  • Brass CA360 construction resists corrosion
  • Rated to 335 psi for hydraulic systems
  • Withstands 250 Degrees F operating temperature
  • Pack of 10 fittings for multiple connections

4 mm Brass Compression Union

This pack contains ten straight compression unions designed to join two 4 mm metric tubes. Each fitting is machined from CA360 brass for use in chemical, hydraulic and general fluid-transfer systems. The straight connector shape allows in-line assembly without changing flow direction.

Operating Pressure and Temperature Limits

The fittings are rated for a maximum operating pressure of 3,335 psi and a maximum operating temperature of 250 degrees Fahrenheit. These values define the practical envelope for any system that incorporates the unions. Exceeding either limit can compromise seal integrity and fitting strength.

CA360 Brass Material Grade

The material grade CA360 determines corrosion resistance, machinability and mechanical strength in the intended fluid environment. Buyers who need a different alloy for specific chemical compatibility should select an alternative fitting.

Questions about this item

Should I buy the 10-pack or look for a different quantity?

The listing supplies exactly 10 brass unions in one pack, so you receive ten pieces per order.

What does the 335 psi rating mean when the fitting is installed?

The joint is tested to hold up to 335 psi at the maximum operating temperature of 250 °F without leaking.

How does the 4 mm compression interface limit tube choice?

Both ends accept 4 mm outer-diameter tube and seal by compressing a ferrule onto that exact size.
