1PC 128mm Hose OD Brass Straight 2 Way Pipe Fitting Barbed Reducer Connector Coupler A simple, rugged brass barbed reducer that lets you join a 12 mm outerdiameter hose to an 8 mm outerdiameter hose in a straight, inline connection. Designed for easy installation and a reliable mechanical grip, this coupler is ideal for repairs, retrofits, and builds where two different hose sizes must be joined without adapters. Key benefits Secure, lowprofile connection: barbed ends hold hoses in place for a tight mechanical fit; use hose clamps for added leak resistance. Durable material: brass construction provides corrosion resistance and long service life in typical water, air and noncorrosive fluid applications. Fast installation: pushfit assembly — no special tools required for initial fitting, reducing service time. Compact, straight design: maintains a clean inline run and minimizes flow disruption when connecting two hose sizes. Key attributes Quantity: 1PC (one piece) Functionality: straight 2way reducer / coupler for joining two hoses Compatibility: fits hoses with 12 mm and 8 mm outer diameter (OD) Material: brass Type: barbed connector / reducer Typical applications Home plumbing and irrigation: connect different sized garden, drip or appliance hoses for watering systems and repairs. HVAC, pneumatic and small equipment lines: join lowpressure air or condensate lines where hose size transitions are required. Aquariums, water features and hobby projects: reliable connection for water tubing in tanks, pumps and filtration systems. Installation tips Push the hose fully onto the matching barb; orient larger hose to the larger barb and smaller hose to the smaller barb. Secure each hose with a suitable clamp (wormgear or spring clamp) for sealing performance. Use in appropriate low to mediumpressure systems and compatible fluids only; inspect periodically for wear. This brass 128mm barbed reducer is a straightforward, longlasting solution when you need a neat, dependable transition between two common hose sizes.
