1/8 MPT Hex Pipe Plug Black

The 1/8 MPT Hex Pipe Plug Black from FRAGOLA is an essential component for automotive builders and mechanics managing fluid systems in custom engine bays, fuel systems, or hydraulic lines. This plug is crucial for ensuring that unused NPT ports do not leak or invite contamination, which can degrade system integrity.

Designed with a tapered NPT thread profile, this black hex plug creates a reliable metal-to-metal seal without the need for sealant tape or thread dope. The hex head shape allows for easy installation and removal, preventing thread stripping in tight spaces. Its black finish not only resists oxidation but also enhances the aesthetic of modern engine compartments.

This plug is particularly beneficial for professional fabricators and DIY tuners during engine swaps, fuel system prototyping, or consolidating multiple pump feeds into a single supply rail. Its compact design ensures minimal space occupation while maintaining system pressure and cleanliness.
