Value Brand 1 in MNPT x FNPT Red Brass 45 Degree Street Elbow Class 125 200 psi 4140 Steel
A 45-degree red brass street elbow connects 1-inch male and female NPT threads at 200 psi using 4140 steel
- TypeOther
- 45-degree angle enables smooth directional changes in piping systems
- Red brass construction resists corrosion for durable plumbing connections
- Class 125 rating supports standard residential and commercial pressure requirements
- 200 psi maximum operating pressure handles demanding fluid transfer applications
- 4140 steel material provides high strength for reliable long-term performance
Application & User
This 45 degree street elbow connects a male NPT thread to a female NPT thread in plumbing systems. It suits installers who need a compact directional change in water or gas lines. The red brass construction resists dezincification in potable water applications. Builders working to Class 125 pressure requirements will find it specified for the job.
Build & Connections
The fitting is machined from 4140 steel for mechanical strength under pressure. Male and female NPT threads allow direct assembly without extra couplings. A 200 psi maximum operating pressure rating covers standard residential and light commercial service. The 45 degree sweep reduces flow restriction compared to sharper bends.
Upgrade Context
This elbow replaces a separate elbow and nipple combination, saving labour and potential leak paths. The jump is worth it when a single-piece street elbow simplifies a tight installation. Buyers who need a different thread standard or a higher pressure class must select an alternative fitting.

Questions about this item
What does the NPT thread standard mean for the 1 in male and female ends?
NPT threads are tapered so they seal as they tighten; the 1 in male and 1 in female ends on this elbow will mate with any matching NPT pipe or fitting without adapters.
How much space does the 45 degree street elbow need behind the wall for the male end to clear?
The street pattern puts the male NPT end on the short radius of the 45 degree bend, so you need roughly the fitting’s own length plus thread engagement behind the finished surface for the male end to clear.
Should I use thread tape or pipe dope on the NPT joints, and which end goes on first?
Apply PTFE tape or pipe dope to the male threads only, then thread the male end into the female port first; tightening the female end onto the male afterward avoids cross-threading the street elbow’s shorter male shank.
