Legris 3699 04 10 4mm Tube BSPP Brass Male Swivel 90° Elbow

4mm Tube BSPP Brass Elbow

The Legris 3699 04 10 fitting connects 4mm tube to a BSPP 1/8 inch port with a nickel-plated brass 90-degree swivel elbow. It suits pneumatic or fluid systems where a compact right-angle joint is needed and the swivel action eases alignment during assembly. The fitting handles a maximum pressure of 435 psi and an operating temperature range from -4 to 302 degrees Fahrenheit. Installers who need a corrosion-resistant elbow for tight routing will find it appropriate.

Check Thread Size and Tube OD

Verify that the port uses a BSPP 1/8 inch thread and that the tubing outside diameter is 4mm, which corresponds to 5/32 inch, before ordering. The swivel male end requires a matching female BSPP port with a sealing washer or O-ring seat for a leak-free joint. Confirm the system pressure does not exceed 435 psi and the media temperature stays within the -4 to 302 degrees Fahrenheit range. A 13mm hex spanner is required for installation, so ensure tool access at the mounting location.

Replaces Fixed 90-Degree Elbows

This swivel elbow replaces fixed 90-degree fittings when installers need rotational freedom to orient the tube after tightening the thread. The jump is worth it on machines where vibration or thermal cycling makes rigid elbows prone to stress leaks, and where the nickel-plated brass material resists the media better than plain brass or steel alternatives. It does not suit applications requiring a straight-through flow path or a bulkhead mounting style. Buyers who need a non-swivel fixed elbow or a different thread standard should select another fitting.
