The Beduan 1/4" NPT Stainless Steel Female Bulkhead Coupler is a reliable, high-quality solution for creating secure, leak-resistant connections through panels, tanks, or enclosures. Designed for demanding applications, this thru-bulk pipe fitting offers both durability and precision, making it ideal for industrial, commercial, and DIY fluid or air systems. Manufactured from premium 304 stainless steel, this bulkhead coupler delivers excellent corrosion resistance and maintains strength and ductility even at elevated temperatures. It is well-suited for use in harsh environments, including those exposed to moisture, chemicals, or outdoor conditions.

Please note that the included metal washer is not stainless steel. The coupler features a 1/4" NPT female inner thread, providing a standard, secure connection interface compatible with a wide range of fittings, hoses, and components. Its full female thread design across the 1-1/2" body length allows for flexible installation options and dependable sealing. On the outside, the fitting has an outer diameter of 20.96 mm, equivalent to 1/2" BSP, ensuring a snug fit in appropriately sized mounting holes and bulkhead openings. This bulkhead coupler is easy to install and integrate into new or existing systems. It is commonly used in air compressors, pneumatic systems, hydraulic lines, water and coolant circuits, fuel systems, and various custom setups where a robust, pass-through female connection is needed. Whether you are building equipment, upgrading a system, or performing repairs, the Beduan 1/4" NPT Stainless Steel Female Bulkhead Coupler provides the strength, reliability, and performance you can trust from a precision-engineered stainless steel fitting.
