Male Connector 4 mm to 3 mm

The Legris 3101 04 09 is a push-fit adapter fitting designed for vacuum applications. It connects a 4 mm tube outer diameter on side A to a male metric 3 mm pipe on side B. The brass body is supplied in a pack of 10 pieces for plumbing or pneumatic installations.

Sustained pressure and temperature limits

The fitting withstands a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees F. These ratings apply to continuous service rather than brief peaks, so the connector maintains its seal under steady vacuum or fluid flow within the stated envelope.

Brass construction and sealant status

The brass material resists corrosion in typical plumbing environments and the silver finish is standard for this alloy. No pre-applied thread sealant is included, so the installer must add a compatible sealant to the M3 x 0.05 threads to achieve a leak-free joint at the rated pressure.

Questions about this item

How much heat can the 3101 04 09 male connector handle during continuous operation?

The brass fitting is rated for a maximum operating temperature of 175 Degrees F, so it remains stable in typical vacuum or fluid lines that run warm all day.

Which tubing and thread sizes must I already have for this push-fit adapter to seal properly?

You need 4 mm outer-diameter tubing for the push-to-connect side and a M3 x 0.05 male metric thread on the mating port.

Will the 3101 04 09 connector work with older brass fittings that use the same 3 mm pipe size?

Yes, the Side B connection is a standard 3 mm male metric thread, so it mates with legacy ports of that size without adapters.
