Professional Applications & Engineering Value

This black-coated steel pipe adapter solves critical challenges in industrial fluid and gas transfer systems where BSPT to NPT conversion is required. The welded construction combined with Schedule 40 wall thickness provides exceptional burst pressure resistance, preventing failures in air, natural gas, oil, steam, and water applications. The threaded both ends design maintains seal integrity while the black coating protects against corrosion in humid or chemical-exposed environments. Engineers specify this adapter for its ability to bridge international piping standards without compromising pressure rating or requiring system modifications, making it ideal for petrochemical, manufacturing, and utility installations where dual-thread compatibility and durable steel construction are paramount.

Specification Summary & Compliance

Manufactured to ASME B1.20.1 thread standards with dimensional compliance to ASTM A53 and ASTM A733 specifications. Features Class 2A/ISO tolerance threading on both ends with precise 1/2" NPT × BSPT connections. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives. The 4" length with 0.11" wall thickness maintains Schedule 40 pressure ratings across the specified service media.
