Frequently Asked Questions

AI
NPT (National Pipe Tapered) threads are tapered to create a seal as they are tightened, common in North America. G threads (Parallel) are straight and typically require a washer or O-ring to prevent leaks.
Stainless steel (specifically 304 or 316 grade) offers the highest corrosion resistance. Brass is a strong alternative for water and gas, while PVC is ideal for lightweight, non-corrosive fluid transport.
For tapered threads like NPT, using PTFE (Teflon) tape or pipe dope is essential to fill gaps and ensure a watertight seal. Parallel threads usually rely on gaskets or seals.
