  • Quick push-fit connection saves installation time
  • Brass C36000 construction resists corrosion and handles 435 psi
  • 12 mm tube size on both ends joins equal lines
  • Rated to 302 °F for demanding fluid systems
  • Compact 50 mm length fits tight plumbing spaces

Brass Push-Fit Union for 12 mm Tubing

This Legris 3606 fitting joins two lengths of 12 mm tube using push-to-connect ends on both sides. The brass body is rated to 435 psi and 302 degrees F, making it suitable for lubrication lines and similar fluid circuits. It installs without tools and arrives new.

Tool-Free Connection in Tight Spaces

The 50 mm overall length lets the union sit between components where a threaded coupling would need a wrench. Each end accepts 12 mm outer-diameter tube and grips on insertion, freeing the installer from sealant tape or flare nuts. No thread sealant is pre-applied or included.

Replaces Threaded or Compression Unions

Swapping a threaded brass union for this push-fit model cuts assembly time and removes the risk of cross-threaded joints. The upgrade is worthwhile when the circuit runs at or below 435 psi and 302 degrees F and when 12 mm tube is already specified. It does not suit applications needing larger-bore tube or higher pressure ratings.

Questions about this item

What is the maximum operating pressure before the 12 mm brass fitting leaks?

The fitting is rated for a maximum operating pressure of 435 psi, so sustained use above that value risks leakage.

How hot does the brass body get when fluid runs at the 302 °F limit all day?

At the maximum operating temperature of 302 °F the brass body will reach the fluid temperature, so expect the fitting to be too hot to touch.

Which tube outer diameter must I already have for the push-to-connect ends to seal?

Both ends accept 12 mm outer-diameter tube, so you need 12 mm tubing for a proper seal.
