This 1/4" stainless steel compression fitting end cap is an essential component for sealing off tubing lines in plumbing, hydraulic, and pneumatic systems. Designed with precision-engineered ferrules included, this fitting creates a secure, leak-resistant seal when properly tightened. The compression design allows for easy installation without the need for welding or soldering, making it ideal for both professional contractors and DIY enthusiasts. Constructed from durable stainless steel, this end cap resists corrosion and withstands demanding conditions, ensuring long-lasting performance in residential, commercial, and industrial applications. The hexagonal body provides a firm grip for wrench tightening, while the included ferrules compress against the tubing to form a tight, reliable connection. Perfect for capping off unused lines, terminating runs, or creating temporary closures in fluid transfer systems. The quarter-inch size fits standard compression tubing and is compatible with various liquids and gases within appropriate pressure ratings.
