Clean the port; remove debris or old sealant before installation.

Inspect threads when servicing; replace the plug if threads are worn or damaged.

Frequently Asked Questions

It’s a 3/8″ NPTF pipe plug (OEM). NPTF is a tapered pipe thread designed for pressure-tight, seal-on-thread connections.

It fits many Graco models (see the Compatible Machines list above). Always confirm your machine’s parts diagram for a 3/8″ NPTF plug location before ordering.

Using the wrong thread (e.g., BSP instead of NPTF) can damage the port and cause leaks or pressure loss. Match thread type and size exactly.
