The ISO Pipe Thread Standard is internationally recognized and widely used in Europe, Asia, and other global markets for fluid, gas, and mechanical connections. It includes two main types of threads: ✔ ISO G Thread (Parallel – BSPP Equivalent) – Straight (parallel) threads requiring a sealing washer or O-ring for leak-proof connections.✔ ISO R Thread … Read more
The National Pipe Straight (NPS) thread is part of the American National Pipe Thread (NPT) family, but unlike NPT (which is tapered), NPS threads are parallel (straight). This means NPS threads do not provide a pressure-tight seal on their own and require sealing washers, O-rings, or gaskets to ensure a leak-proof connection. NPS is commonly … Read more
The National Pipe Thread (NPT) standard is widely used in the United States, Canada, and other regions for plumbing, hydraulic, and gas connections. Unlike parallel threads, NPT threads are tapered, which allows them to create a tight, leak-proof seal without requiring additional sealing elements like O-rings. NPT is governed by ANSI B1.20.1, with variations including:✔ … Read more
The British Standard Pipe (BSP) thread is a widely used thread standard for pipe fittings in the UK, Europe, Asia, and many other regions. It is primarily used in water, gas, and hydraulic systems to provide a secure, leak-proof connection. BSP threads come in two variations: ✔ BSPP (British Standard Pipe Parallel, also known as … Read more
The British Standard Whitworth (BSW) thread was one of the first standardized thread forms and is still used in mechanical engineering, vintage machinery, and construction. It features a 55° thread angle, which is different from the 60° Unified Thread Standard (UTS) used in UNC, UNF, and UNJ threads. Although BSW has largely been replaced by … Read more
