FPC Series-Threaded Straight Through

The FPC Series threaded straight through fittings are designed to streamline pneumatic tubing connections through a combination of user-friendly installation features and robust sealing mechanisms. These fittings prioritize ease of use without compromising the integrity of the connection under typical industrial operating conditions.

A quick-lock mechanism serves as the primary interface for tube insertion and removal. When the tubing is inserted, an internal gripping component automatically engages, securing the tube without requiring any additional tightening or manipulation. Disassembly is equally straightforward, accomplished by pressing the locking sleeve inward while withdrawing the tubing. This operation can be performed using only one hand and requires no specialized tools, reducing assembly time and simplifying maintenance procedures where tubing replacement or rerouting may be necessary.

Thread sealing has been addressed through pre-application of sealant on the threaded portions of the fitting body. This eliminates the need for installers to wrap Teflon tape or apply liquid sealant during assembly, reducing variability in installation quality and decreasing the risk of leaks due to improper sealing technique. For the smaller M5 thread size, a sealing gasket is provided as standard, offering an additional layer of leak prevention suited to the dimensional constraints of miniature fittings.

The tube retention and sealing system employs a dual-element design to maintain connection integrity under various operating conditions. An O-ring provides the primary seal around the tube exterior, preventing air leakage along the interface between the tube outer wall and the fitting body. A stainless steel snap ring functions as the mechanical retention element, engaging with the tube surface to resist pullout forces. This combination of sealing and gripping elements helps prevent tube detachment even in applications subject to vibration or pressure fluctuations, while maintaining leak-free performance over extended service periods.

The straight through configuration permits flow in either direction with minimal pressure drop, as the internal passage maintains consistent diameter without abrupt changes or restrictions. This design characteristic suits applications where maintaining flow efficiency is a consideration. The threaded connection interface accommodates standard port configurations, allowing integration with common pneumatic components without requiring adapters.

The FPC Series construction materials are selected to resist corrosion and wear in typical industrial environments, contributing to consistent performance across the product lifecycle. The combination of tool-free tube handling, pre-sealed threads, and dual-element tube retention positions these fittings as practical components for pneumatic systems where installation efficiency and connection reliability are valued.
