                                                  Which Threads Can We Manufacture & Thread Introduction

 

Note :Below is a detailed introduction to the world's mainstream thread standards (NPT, BSPT, BSPP, UNC, UNF, NPTF, ISO) to help you quickly clarify your needs. At the same time, you can learn that we have OEM customization capabilities for the full range of threads, which can be accurately produced according to your specific requirements to meet the application needs of different countries and scenarios

 

Thread Type	Full Name	Core Standards	Thread Angle	Taper	Applicable Countries/Regions	Sealing Method
NPT	National (American) Pipe Thread	ASME B1.20.1	60°	1:16	North America (USA, Canada, Mexico, etc.)	Metal-to-metal contact + sealing glue/PTFE tape
BSPT	British Standard Pipe Taper	ISO7/EN 10226	55°	1:16	UK, most EU countries, Australia, Middle East, Singapore, India, etc.	Taper engagement + PTFE tape
BSPP	British Standard Pipe Parallel	ISO 228-1	55°	None (parallel)	Europe/ UK	Sealing ring (end face sealing)
UNC	Unified National Coarse	ANSI B1.1	60°	None (parallel)	North America (USA, Canada, etc.)	No built-in sealing (for mechanical connection only)
UNF	Unified National Fine	ANSI B1.1	60°	None (parallel)	Same as UNC	No built-in sealing (better tightness than UNC)
NPTF	National Pipe Thread Fuel	ASME B1.20.3	60°	1:16	North America	Dry seal (interference fit, no need for sealing materials)
ISO	Metric thread	ISO261/ISO 965	60°	Parallel or 1:16 (taper)	Global	Sealing ring or metal-to-metal contact (depending on type)

 

Working Together

We cooperate closely with customers to ensure products meet industry standards and regulations. We also assist in JIT, Kanban and other lean manufacturing solutions to optimize supply chains and reduce costs.

In product development, we adopt a partnership approach, using in-house design facilities for assessments and providing prototype and pre-production sampling support to meet your expectations.

 

Quality Commitment

Customers can rest assured we adhere to their high standards. With ISO 9001 accreditation, we implement strict full-process quality control. Using material analyzers and thread gauges, we rigorously inspect raw materials, semi-finished and finished products for safety and reliability.

 

Supporting Sustainability

Our production integrates sustainability: we use recycled materials where possible and recycle all scrap to minimize environmental impact.

With ISO 14001 accreditation, we work with you to achieve your environmental objectives and promote green development.
