Product Identity

The Banjo SL300-90 is a 3-inch Schedule 80 polypropylene street elbow with a 90-degree FNPT by MNPT connection. It is built for fluid-handling systems that require a durable, corrosion-resistant change of direction.

Fit and Alternatives

This fitting suits installers who need a black Schedule 80 elbow rated for 150 psi across a temperature range of -20 to 150 degrees F. It is not for systems that require a different pipe size, connection type, pressure class or material grade.

Deciding Specification

The Schedule 80 wall thickness combined with a 150 psi pressure rating at the stated temperature range determines whether this elbow meets the design requirements of the installation.

Questions about this item

What size pipe thread does the 3 in FNPT x MNPT connection require?

The elbow uses a 3 in FNPT female thread on one end and a 3 in MNPT male thread on the other, both matching Schedule 80 dimensions.

How do I install the 90° street elbow without cracking the polypropylene body?

Hand-tighten the male NPT end into the female fitting, then turn one to two full turns with a strap wrench; do not use pipe wrenches directly on the black body.

When should I replace the Schedule 80 street elbow in a 150 psi system?

Inspect annually for stress whitening, thread deformation or leaks; replace immediately if the fitting sees temperatures above 150 °F or pressure above 150 psi.
