Beswick Engineering Co. Inc. offers stainless steel barb and push-to-connect fittings in a variety of configurations and thread sizes. These fittings are machined using corrosion resistant stainless steel, and common thread sizes include 10-32, M3, M5 and ¼-28 thread.
All of the external threads incorporate an O-ring face seal which provides a leak-tight seal. Buna-N is the standard material assembled into the O-ring grooves. If another material is required, due to exposure to extreme temperatures or harsh chemicals, Beswick offers a wide range of optional O-ring materials such as (Fluorcarbon, Silicone, Ethylene Propylene, Fluorosilicone, Teflon®, and Aflas®).
