NPT and NPTF Tapered Pipe Threads

NPT and NPTF pipe thread applications range from electrical conduits to high-pressure piping carrying natural gas and chemically aggressive liquids. Both thread types use a thread taper that provides solid and vibration-resistant connections. While NPT threaded plastic fittings are standard and readily available, there are distinctly specific installation and ...

Durometer affects what type of materials and fittings you use for your application

What is durometer?

Durometer or Shore durometer is a standardized way to measure the hardness of materials like rubber (elastomers) and plastics. Durometer measurement scales range from 0 to 100 but there is no such thing as a durometer unit of measurement. Another way of saying this is that durometer is a dimensionless ...

Luers for medical applications and the new ISO 80369 small-bore connector standards

What is ISO 80369 and how does it relate to luers?

The ISO 80369-7: Connectors for Intravascular or Hypodermic Applications standard for luer fittings is part seven of ISO 80369. ISO 80369 is a series of medical device standards developed by the International Organization for Standardization. The standards cover small-bore connectors used in the different systems providing direct, individual patient care. ISO 80369 standards were developed to significantly improve ...

There is more to heat seal than just dwell time, temperature and pressure

United Silicone metal bonded silicone sheets.

An introduction to heat sealing. Heat sealing is a critical process used for rigid and flexible packaging of all kinds. Heat conduction or heat transfer sealing uses heated seal heads or sealing bars to adhere, attach or close film to film or film to a rigid container. The results are leak-proof seals for bags, pouches ...

Quality component parts: OE, OER, OEM and ODM and what they mean

OEM stands for Original Equipment Manufacturer. Most often, OEMs purchase parts from other manufacturers or suppliers and use them to assemble their finished products. OEMs also make parts and sub-assemblies that are resold to other companies who assemble them into their own finished products.

Introduction
The acronym OEM has come to be associated with product engineering and manufacturing, sub-assembly manufacturing (especially automotive and electronics) and even ...

The new ISM Vacuum Pressures Unit Conversions Chart (Absolute and Relative) is now available as a downloadable PDF

Introduction
Vacuum systems are used in a wide range of industrial, material handling, food processing and laboratory applications. Wherever vacuum is used, questions come up about vacuum or negative pressure. What it is, how it is measured and how one vacuum measurement unit compares to another.

The new Vacuum Pressures Unit Conversions Chart from ISM was created to help make component selection for vacuum applications faster and ...

Ensuring a gas or liquid-tight connection means understanding tapered pipe threads

NPT, National Pipe Taper (American) and BSPT (British standard Pipe Taper) are tapered pipe thread standards. Male and female tapered pipe threads wedge themselves together but need a sealant for a completely leak-free connection. Sealants fill any voids between the threads that could travel along the thread spiral.

Tube and pipe are not the same thing
Tube and pipe are hollow structures designed to provide a path for the flow of fluids or  ...
