FAQ
Q: What sealing method works best with these bushings?
A: Use PTFE tape or pipe compound rated for your specific temperature and fluid requirements. The tapered BSPT threads require proper sealant for optimal performance.
Q: Can these connect to NPT fittings?
A: No. NPT uses 60° thread angles while BSPT uses 55°. Mixing these standards will cause leaks and thread damage.
Q: Why choose black finish over galvanized?
A: Black iron works better for gas and steam applications. Galvanized coatings can flake and damage sensitive equipment components.
Q: What pressure ratings apply?
A: Standard ratings include 150 PSI for steam and 300 PSI for water, oil, and gas at ambient temperatures.
