4mm Tube BSPP Nickel Brass Elbow

The Legris 3699 04 13 fitting is a 90 degree male elbow that joins a 4mm tube to a BSPP thread. High phosphorus chemical nickel plating resists abrasion, chemicals and corrosion. The component is FDA approved for food processing environments. It is supplied new and ready for immediate installation.

Suited for welding spatter and food lines

This elbow suits systems exposed to weld spatter or aggressive chemical contact where standard fittings degrade. Builders needing a straight connector, a different thread standard or a larger bore should select an alternative fitting. The Proposition 65 warning also makes it unsuitable for projects that must avoid listed substances entirely.

Nickel plating and regulatory approvals change

The chemical nickel finish extends service life in harsh industrial atmospheres without additional coatings. FDA acceptance allows direct use in food grade circuits without extra certification steps. The California Proposition 65 notice requires safe handling procedures and proper labelling in affected jurisdictions.

Questions about this item

What tube diameter and thread size must my existing line and port have for this 4 mm tube by BSPP elbow to seal properly?

The fitting accepts a 4 mm tube on one end and a 1/4 inch BSPP male thread on the other, so both the tube and the mating port must match those dimensions.

Will the nickel-plated brass body resist corrosion if I keep it connected to older steel pipework in a damp workshop?

The high-phosphorus chemical nickel plating resists abrasion, chemicals and corrosion, making it suitable for aggressive environments including contact with dissimilar metals.

How can I confirm the joint is leak-tight after I push the tube into the elbow and thread it into the port?

Pressurise the system to its working pressure and inspect the tube-collet seal and the BSPP thread interface for any fluid escape; the FDA-compliant design is intended to remain intact under normal service conditions.
