Flexible Stainless Steel Air Compressor Intake Hose with Brass Check Valve (F14 x 5 mm) Key benefits Durable, corrosion-resistant construction: Hose made from high-quality stainless steel and the check valve made from solid brass for long service life in workshop and field conditions. Prevents backflow and protects your compressor: Built-in brass check valve controls airflow and prevents reverse flow, reducing the risk of contamination or damage to the compressor. Fast, simple installation: F14 x 5 mm hex nut connection fits compressors that use this standard size, enabling quick replacement or retrofit without special tools. Compact, usable length: 280 mm overall length gives sufficient reach for common compressor layouts while keeping the intake line neat and secure. What it does and why you need it Replaces worn or damaged compressor intake pipes with a robust stainless steel line that resists kinks and corrosion. The brass check valve (10 x 14 x 16 mm) provides reliable one-way airflow control to maintain proper compressor operation and protect internal components. Ideal for oil-free compressors where a clean, corrosion-resistant intake and dependable check valve are important for performance and longevity. Specifications Hose material: High-quality stainless steel Connection: Hex nut F14 x 5 mm Length: Approximately 280 mm total Check valve material: Brass Check valve dimensions: 10 x 14 x 16 mm Typical use: For connecting oil-free air compressors and similar equipment Practical use scenarios Home workshop: Replace a brittle or clogged intake hose on a portable oil-free compressor to restore reliable airflow for airbrushes, tire inflation, and pneumatic hand tools. Jobsite or mobile service: Install as a durable replacement intake line on a compact compressor used in field repairs, keeping the system protected from backflow and debris. Maintenance and upgrades: Fit to an oil-free compressor during routine service to upgrade the intake connection to a corrosion-resistant stainless steel hose with a precision brass check valve. Why choose this component Matches the original function and dimensions for direct compatibility with compressors using F14 x 5 mm fittings. Stainless steel plus brass offers a balance of strength, corrosion resistance, and reliable valve performance without replacing larger assemblies. Simple to fit and immediately restores safe, one-way intake flow. Packaging note Supplied as a flexible stainless steel intake hose with integrated brass check valve sized as specified.
