How to Choose Galvanized Malleable Fittings
Start with the job the fitting needs to perform, then confirm the connection size, configuration, thread compatibility, length where applicable, and stated pressure designation. The products represented here include fittings for right-angle turns, compact threaded joins, pipe extension, size transitions, connection closure, and joining compatible pipe connections.

Use 90° elbows and street elbows to change a pipe run at a right angle. Choose couplings to join compatible pipe connections, bushings to transition between stated sizes, plugs to close an applicable connection, and nipples to join or extend threaded components.
Confirm size, shape, and threads
Compare the nominal size or stated size transition first. Then select the required configuration, such as elbow, coupling, hex bushing, cored plug, or nipple. For threaded connections, verify the listed FNPT or MNPT connection type against compatible mating components.

Plan the right fit before choosing
Choose the fitting configuration before comparing sizes
A fitting’s shape determines how it works within a threaded pipe assembly. Select a component that directly addresses the planned connection or route.
- 90° elbows redirect a pipe run around a corner.
- Street elbows provide a compact option for a right-angle change in direction.
- Couplings join compatible pipe connections.
- Hex bushings adapt between two stated connection sizes.
- Cored plugs close an applicable connection.
Use close or measured-length nipples for the planned layout
Galvanized steel pipe nipples are represented in close configurations and in stated lengths. A close nipple is intended for compact threaded connections, while listed length options provide a defined connection point between threaded components.
- Close nipples are represented in 1/2 in., 3/4 in., and 1 in. sizes.
- Measured nipple examples include 1/2 in. x 3 in., 3/4 in. x 6 in., and 2 in. x 4 in.
- Match the listed size and length to the compatible piping layout.
- Review MNPT listings where threaded compatibility is required.
Check pressure designation and product details
After selecting the fitting type and size, review the product’s listed pressure rating or designation and construction details. The products represented in this category are listed at 150 PSI, with lead-free designations on the summarized products.
- Review the 150 PSI rating or designation for the specific product.
