Frequently Asked Question
What is an NPT pipe plug?
An NPT pipe plug is a threaded component used to seal off unused ports or fittings. It features national pipe thread tapering, which ensures a tight, leak-free seal in high-pressure systems using standard pipe thread sizes.
How do you connect a NPT pipe?
To connect a NPT pipe, align the NPT threads of the male and female parts, then tighten using a wrench. A sealant or thread tape is often applied to ensure a leak-free connection in pressurized pipe thread systems.
Can you use a straight thread with NPT?
No, straight threads are not compatible with NPT threads. NPT plugs rely on a tapered pipe thread to form a seal, whereas straight threads require a gasket or O-ring. Mixing the two could lead to leaks or poor fitment.
What is a hex pipe plug?
A hex pipe plug is a type of pipe plug with a six-sided head, allowing for easy tightening with a wrench. Often used in NPT pipe applications, it's designed to close off ports while ensuring a secure, durable seal.
What do you use to plug a water pipe?
To plug a water pipe, use an NPT pipe plug with matching pipe thread and apply thread sealant or tape. NPT plugs with national pipe thread tapering are ideal for water systems, ensuring a snug, leak-proof closure.
