Stainless Steel Street Elbows
A stainless street elbow is a 90° stainless elbow with one female-threaded end and one male-threaded end. The male spigot screws directly into a stainless valve, pump or fitting port.
It turns the line without an intermediate nipple at instrument fittings, sampling valves and process equipment outlets. 12 sizes from 1/8″ to 4″ are available in AISI 304, plus a 1/4″ option in AISI 316.
Main Applications
- Sampling and drain valve outlets
- Changes of direction at gauge and sensor fittings
- Short turns at pump and filter ports
- Threaded ports on tanks and reactors
- Equipment connections in food lines
- Water and air outlets in marine environments

| Suitable media | Food, drinking water, mild chemicals | Chloride-containing water, seawater, aggressive chemicals | Cold domestic water, fire water |
Which material? Because the medium can stagnate in instrument and sampling lines, 316 street elbows are preferred in chloride environments against pitting corrosion.
Advantages

- The spigot screws directly into the instrument port
No Intermediate Nipple
- One less part and one less threaded joint
12 Sizes
- From 1/8″ instrument lines to 4″ process lines
Stainless Integrity
- Connection in the same material as the equipment
Construction and Design Features
- Female-threaded end and male spigot at right angles
- ISO 7-1 R taper thread on the spigot
- Stainless cast body (depending on model)
- ISO 4144 pressure ratings

How to Choose?
- Identify the endsIf one side is a female port choose a street elbow; if both sides are pipe, a threaded elbow.
- Measure the sizeThe spigot and the female end are the same size.
- Plan the final positionThe elbow turns as the spigot is tightened; make sure the female end faces the target direction.
- Choose the gradeUse 316 in chloride environments or with stagnant media.
