  • 45-degree turn redirects flow smoothly
  • Class 300 rating handles 1500 psi at 150 °F

Value Brand 1-1/4 in 45 Degree Elbow Class 300

This malleable iron fitting redirects pipe runs by 45 degrees in high-pressure systems. Rated Class 300, it handles saturated steam at 300 psi and liquid service up to 1500 psi at 150 degrees F. Female NPT threads accept standard 1-1/4 inch pipe. Standards ASME B 16.3 and B 16.4 apply.

Who this suits and who should look elsewhere

Suits installers needing a durable, FM approved and UL listed elbow for steam, water, oil or gas lines within the stated temperature range of -20 to 550 degrees F. Not for systems requiring welded joints, larger pipe diameters, or pressure ratings beyond Class 300. Buyers needing different angles or materials should consider other fitting types.

The specification that decides fit

The 1-1/4 inch FNPT connection size and Class 300 pressure rating determine whether this elbow matches the piping schedule and nominal bore of the existing system. Verify both values against the engineering specification before ordering.

Questions about this item

Does the fitting need any special sealant for the FNPT threads to seal properly?

Use pipe thread sealant or PTFE tape rated for 1500 psi at 150 °F on the FNPT threads to achieve a leak-free joint.

Will the malleable iron elbow resist galvanic corrosion when threaded into my existing brass pipe nipples?

Direct contact between malleable iron and brass can cause galvanic corrosion; use a dielectric union or brass adapter to isolate the metals.

How can I verify the elbow meets the ASME B 16.3 and B 16.4 standards after installation?

Check for the ASME B 16.3 and B 16.4 markings cast on the body and confirm the joint holds 1500 psi at 150 °F without leakage.
