Fitting Details

The Legris 3675 60 18 is a nickel-plated brass male connector designed to join 3/8 in tubing to a matching NPT thread. It withstands up to 435 psi and operates from -4 to 302 degrees F. An FKM gasket seals the joint and an 18 mm hex allows standard tool engagement.

Typical Use Cases

Suits fluid-handling builds that require a corrosion-resistant, high-temperature metal fitting with a straight tube-to-pipe transition. Not intended for installations that demand an elbow, tee or bulkhead configuration, nor for systems exceeding the stated pressure or temperature limits.

Deciding Specification

The 3/8 in tube and pipe size combined with the 435 psi pressure rating determines whether this connector matches the line dimensions and safety margin required by the circuit.

Questions about this item

What size hex is needed to tighten the 18 mm fitting on the Legris 3675 60 18?

The fitting has an 18 mm hex, so use an 18 mm spanner or adjustable wrench to secure it without rounding the corners.

Which thread sealant works with the FKM gasket on this 3/8 in male connector?

Apply PTFE tape or a non-hardening pipe thread compound to the 3/8 in MNPT threads; the FKM gasket handles the tube seal so the threads only need lubrication and leak prevention.

How often should the FKM gasket be inspected or replaced on this nickel-plated brass trap?

Inspect the FKM gasket annually or whenever the system is opened; replace it if you see cracks, hardening or permanent compression set from the 302 °F upper temperature limit.
