Review: Needed something to hold the pneumatic type tubing (really filament guide in my case) securely to the feed area on the print head. The ones used by OEM were fragile and easily loosened in some appliacations. These were perfect. ## Features - Product Name : Push Fit Quick Coupling ;Model : PC4-01;Tube & Thread Size: 4mm (5/32") OD x G 1/8" Thread - Working Pressure: 0-0.9MPa; Maximum Working Pressure: 1.32MPa; Operating Temperature: 0-60℃ - Type: one end is a tube connector, the other end is a male G thread, and a good plug that can withstand larger and stronger pressure without tripping. - Advantage: wear-resistant, lightweight, anti-crush, anti-pressure, anti-corrosion, good sealing performance and long service life. - Connected tube materials: designed to connect polyethylene, nylon and polyurethane tubes.
