BSPT Hosetail 316 Stainless Steel Hose Fitting

Product Overview

This high-quality BSPT hosetail fitting provides a secure connection between a hose and a male BSPT threaded pipe system. Manufactured from corrosion-resistant 316 (CF8M) stainless steel and conforming to ISO 4144, it is designed for reliability in industrial, plumbing, and marine applications. The barbed hosetail ensures a tight grip on the hose (use with appropriate clamp recommended), while the BSPT thread (ISO 7-1) provides a standard tapered connection. Rated for 150lb class and up to 20 bar (300 psi) working pressure.

Note on Sizing: Select the size where the 'Hosetail Size' matches your hose's internal diameter (ID) and the 'BSPT Male Thread' matches your pipe connection thread size. See guide below for details.

How to Select the Right Size

  • Measure the Internal Diameter (ID) of your hose. Match this to the 'Hosetail Size' listed (e.g., 1/2" ID hose requires a 1/2" hosetail).
  • Identify the required Male BSPT thread size for connecting to your pipe system or equipment port.
  • Example: For a 1/2" ID hose connecting to a 1/2" BSP female port, select the "1/2" (12.7mm) Hosetail × 1/2" BSPT Male" option.
  • Note: Some fittings combine different hose and thread sizes (e.g., 5/8" hosetail × 1/2" BSPT). Choose based on your specific requirements. Always use a suitable hose clamp for a secure connection.

Common Applications

  • Connecting flexible hoses to rigid pipework
  • Industrial fluid transfer lines (water, oil, fuel, compatible chemicals)
  • Marine plumbing and fluid systems
  • Agricultural spraying and irrigation equipment
  • Brewery and food processing transfer lines (ensure material compatibility)
  • Compressed air hose connections (check pressure suitability)
  • General plumbing and hydraulic systems
