Frequently Asked Questions
No. It’s a 3/4″ NPT pipe coupling used wherever your Graco system uses 3/4″ NPT ports. Always verify thread size and standard in your parts manual before purchase.
Check your sprayer’s or accessory’s parts manual/spec sheet for 3/4″ NPT. If unknown, measure the fitting and compare to NPT sizing charts; NPT is tapered and measured by nominal pipe size, not outside diameter.
Yes—use thread sealant or PTFE tape compatible with your coating/solvent. Follow Graco’s guidelines and allow cure time if using liquid sealant.
Only if the connected components are rated for the system’s maximum working pressure and are specified as NPT pipe connections. Never mix thread standards or exceed rated pressure.
This part is NPT only. Using it on BSPP/BSPT/metric ports can cause leaks or damage. Source the exact thread standard or use a rated adapter from the OEM.
