Parker Prestoweld Push-to-Connect fittings are weld splatter resistant and silicone free to meet the stringent requirements of the robotic welding industry for pneumatic controls. All fittings feature nickel-plated brass bodies and threads. Pushbuttons are made from a UL94-V0 polymer. The fittings are designed for use with special Parker Microweld tubing. Microweld tubing is an ether-based polyurethane for maximum hydroylytic stability and has a UL-94 V2 flame rating. Microweld tubing does not contain silicone or other contaminants that affect paint surfaces. The Prestoweld fitting is based on the design of the Parker Prestolok push-in fitting, with a silicone free lubricated nitrile o-ring and stainless steel grab ring to ensure positive tube retention. The push-button collet also functions as a protective cover that encapsulates the Microweld tubing.
Parker Prestoweld fittings are available in a range of configurations, including unions, tee's and elbows, with male NPTF threads and straight threads with a fully retained seal. The fittings are rated for a working pressure up to 300 psig and a working temperature from 0° to +200°F.
