NPT 1/4" ISO A Quick COuplings

Interchangeability: Ensures that couplings from different manufacturers will fit and function correctly together.
Performance: Specifies performance criteria such as pressure ratings, flow capacity, and durability requirements.
Safety: Provides guidelines to ensure safe operation under specified conditions, reducing the risk of accidents.

1/4″ NPT Thread

Dimensions: The outer diameter of the 1/4″ NPT thread is approximately 0.54 inches (13.72 mm). The threads are tapered, which means the diameter decreases slightly along the length of the threads.
Thread Specification: NPT threads have a 60-degree thread angle and follow the ANSI/ASME B1.20.1 standard for pipe threads.
Sealing: Achieved by the wedging action of the threads, typically enhanced with thread sealant or tape to prevent leaks.

Ball-locking mechanism: Uses balls that move into place to lock the plug and socket together securely.
Sleeve mechanism: A sleeve that must be pulled back to connect or disconnect the coupling, providing a quick and efficient operation.
Steel Material: Hardened Carbon Steel material, Provides higher strength and is often used in heavy-duty applications.
Trivalent Zinc Plating: Zinc acts as a sacrificial coating, corroding before the underlying metal does, thus protecting the part from rust.
Nitrile Rubber (NBR) Seal Material: Nitrile Rubber (NBR), also known as Buna-N or acrylonitrile butadiene rubber, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. It is renowned for its excellent resistance to oils, fuels, and other chemicals, making it a popular material in various industrial applications. It is the default Seal ring material.
