Parker Hannifins’s Fluid System Connectors Div. is a manufacturer of fittings and valves for applications including water purification, RO, beverage dispensing, vending, pneumatic, automation and plumbing. Brand names include Liquifit, TrueSeal, Fast & Tite and Par-Barb. With a focus on engineering solutions, it works with customers to develop new products or modify products for specific applications.
Understanding the proper applications for various types of connectors is critical when designing a system or installing equipment. Installations can become routine, but it is important to evaluate each situation for new or unusual criteria.
Considering connection criteria for a successful application
Speedfit Test Caps provide a leak-proof seal in conjunction with push-fit fittings for securing PEX, CPVC or copper piping in domestic hot and cold water systems and in hydronic heating applications when a job is in process or interrupted, such as when water needs to be turned back on or when pressure testing a system before appliances are connected. They are easy to install and disconnect without tools. Disconnection should not damage the fitting or piping, and they can be removed at any stage to allow work to continue.
Recently, the U.S. Environmental Protection Agency (EPA) announced it had worked with three New Jersey school districts to successfully lower lead levels in their drinking water. Testing in 2010 and 2011 found elevated lead levels in approximately 8% of the outlets it tested at the Atlantic City, Union City and Weehawken school districts. The districts resolved the problem through a variety of methods, from filtration to replacing fixtures to simply shutting off those outlets. The latest round of testing showed that lead levels were within acceptable EPA limits.
Recently I purchased a food processor. Before using it for the first time, I read the 18-page instruction booklet and watched a 45-minute DVD. I asked myself, “Why do I put so much time and effort into researching how to use a relatively simple device?” The answer came to me immediately: I have been in the product certification business for almost eight years, primarily dealing with NSF/ANSI 61 certifications.
Checking connector certifications to ensure proper end use
Worldwide, engineered plastic connectors and tubing are used in the water quality industry for a host of residential, commercial and industrial applications. From water treatment and filtration to beverage dispensing and ice making, there are several sound reasons for their widespread use.
Low-lead plastic products are ready for federal lead legislation
The EZ-Faucet Adapter II kitchen sink faucet connector is designed for the easy addition of a feed line for point-of-use (POU) applications. Made with chemical-resistant polypropylene, it can withstand pressures up to 150 psi at 70°F. The adapter connects with standard ½-in. NPSM threads to the faucet and supply line, then branches off with a Mur-lok quick-connect for a supply line to a POU device.
Trial and error methods are often used when developing products. Thomas Edison, with 1,093 patents, more than any other inventor, took many products and ideas and made them better. He would merely take a very good product, such as the light bulb, and make it commercially available. The light bulb had already been invented and used in labs, but Edison took the idea and developed it into a cost-effective product that could be sold commercially.
A few savvy tweaks greatly impact product development
Worldwide, countless fluid carrying systems in operation today employ highly engineered plastics to provide the essential elements of any fluid system, be it residential, retail or commercial. These elements include fittings, seals, piping and tubing—all of which today can be engineered from plastics due to considerable advances in materials technology and manufacturing processes.
