Stainless Steel Elbows

Stainless steel elbows change the direction of a stainless pipeline by 90° or 45°. This page brings together AISI 304 and AISI 316 threaded elbows, street (female-male) elbows and butt-weld elbows. The parts are sold under Novus’s own NVS label; each product page carries a size and stock code table.

How to choose a stainless elbow

First decide on the joining method: BSP threaded elbows for threaded lines, butt-weld elbows matched to pipe outside diameter and wall thickness for welded lines. Then choose AISI 304 or 316 for the environment.

AISI 304 or 316? AISI 304 (1.4301) is the general-purpose chromium-nickel stainless steel used for drinking and domestic water, hot water, heating and cooling circuits, compressed air and food plants. AISI 316 (1.4401) contains molybdenum and resists chlorides, sea water and chemicals better; it is recommended for pools, coastal, chemical and outdoor use. Threaded parts have BSP (Whitworth) threads and should not be combined with NPT parts.

Frequently asked questions

How are stainless elbow sizes given?

Threaded elbows use inches (1/2″, 3/4″, 1″…) and nominal diameter (DN15, DN20, DN25…). Butt-weld elbows use outside diameter and wall thickness, e.g. Ø21.3 × 2 mm for 1/2″ pipe.

How do I seal threaded stainless joints?

Use PTFE tape or a stainless-compatible liquid sealant. Over-tightening stainless threads can cause galling; when joining stainless parts to galvanised or carbon steel pipe, a dielectric union is recommended against galvanic corrosion.
