Hex Nipple

DIYE VALVE stainless steel A hex nipple is a threaded connection fitting and a key component for straight-through connections in piping systems. As a professional manufacturer specializing in pipe fittings, we produce this product in our own factory and strictly control quality to ensure that every product meets international standards. Made in China, this product combines high-quality materials and precision machining, making it the preferred choice for small-diameter, low-pressure pipeline connections in both civil and industrial settings.

Unlike traditional connection methods, this Hex Nipple requires no welding or bonding; installation and removal can be completed with just a wrench, significantly simplifying the installation process and facilitating subsequent maintenance. Compared to carbon steel and brass fittings, these pipe fittings offer superior corrosion resistance, high and low temperature tolerance, and a longer service life, effectively reducing replacement frequency and operating costs for users. As a trusted supplier, we are committed to providing high-performance, cost-effective pipe fitting solutions to global customers.

Core Product Features

1. Structural Design

The product features a central hexagonal prism with equal-diameter external threaded sections on both sides. The hexagonal dimensions are compatible with standard adjustable wrenches and open-end wrenches, ensuring even force distribution during clamping. This effectively prevents thread stripping and damage, enabling convenient and labor-saving installation and removal, improving operational efficiency while protecting the thread structure and extending service life.

2. Thread Accuracy and Sealing Performance

The external threads at both ends are precision-machined, resulting in clear tooth profiles and uniform pitch, compatible with mainstream international thread standards such as BSPT (PT), BSPP, and NPT. When used with PTFE tape or rubber sealing rings, a tight engagement is achieved, ensuring reliable and leak-free sealing, suitable for various media transmission needs.

3. Material Advantages

The products are made of high-quality stainless steel conforming to ASTM A351 standards, including CF8 (304) and CF8M (316) materials. They offer excellent corrosion resistance, withstand various chemical media, and exhibit good high and low temperature tolerance, making them suitable for diverse working environments. The surface undergoes professional anti-corrosion treatment, further enhancing durability and making them suitable for harsh conditions such as chemical and marine applications.

Specifications and Customization

Hex Nipple offers a complete range of specifications, with standard sizes from ⅛" to 4", and mainstream sizes from DN15 to DN50 (1/2 inch to 2 inches). They fully comply with national and American standards for common thread types, and have a working pressure of 150LB, making them suitable for low-pressure piping systems in various fields.

In addition to standard equal-diameter hexagonal fittings (with identical thread specifications at both ends for straight-through connections of pipes of the same diameter), we also offer customization services. We can customize reducing hexagonal fittings (one end larger, one end smaller) to meet the connection needs of pipes with different diameters.

Application Areas

With its superior performance and reliable quality, this product is widely used in small-diameter, low-pressure pipelines, covering industries such as water supply and drainage, gas transmission, chemical, medical, food, marine, and HVAC. It is suitable for the transmission of fluids such as cold water, hot water, gas, oil, and chemical media, and can adapt to harsh civil and industrial conditions, providing stable and reliable connection support for various pipeline systems.
