FAQs

The plug uses a 1-11.5 NPTF taper thread with Class 3 tolerance for precise sealing without auxiliary sealants.

The Graco 121497 PlugHeadless is certified for continuous service up to 5,000 PSI.

Inspect the plug and port threads every 500 hours or after system purges. Apply PTFE-based tape or thread lubricant during reinstallation to prevent galling.
