Frequently Asked Questions

1/4" NPT stands for 1/4 inch National Pipe Taper, which is a standard thread type used in pipe fittings. The tapered threads create a seal when tightened, making them ideal for fluid and air applications in sprayer systems.

This 116658 fitting is commonly used at pump outlets, manifold connections, pressure gauge ports, and anywhere a 1/4" NPT male connection is needed to join hoses or components in the fluid path of compatible Graco sprayers.

For NPT threads, use Teflon tape or liquid pipe thread sealant compatible with your spray materials. Apply sealant to the male threads only, starting 1-2 threads from the end to prevent contamination of the fluid system.

NPT fittings should be hand-tight plus 1-3 turns with a wrench, depending on size. The tapered threads create the seal as they wedge together. Avoid over-tightening, which can damage threads or crack components. The fitting should be snug but not forced.
