5 pcs 1-1/2″ Barb x 1-1/2″ NPT Male Connector, Plastic Hose Barb Fitting, Adapter, Industrial Hose to Pipe Fittings Connect

Description

Product Overview

The ALKARAMA 1-1/2″ barbed to 1-1/2″ NPT male connector set is engineered for seamless integration between flexible hoses and rigid pipe systems. Crafted from high‑impact polypropylene, each fitting offers superior resistance to chemicals, UV exposure, and mechanical stress, ensuring long‑term durability in demanding environments. The set includes five identical connectors, each featuring a precise 1-1/2″ barb on one end and a matching 1-1/2″ NPT male thread on the other, providing a secure, leak‑free seal when paired with standard pipe threads.

Designed with a temperature operating range from –4°F to 248°F, these connectors maintain structural integrity across extreme cold and heat conditions, making them suitable for a wide variety of industrial, agricultural, and residential applications. The connectors are rated for a maximum working pressure of 100 psi, offering reliable performance in low‑ to medium‑pressure fluid transfer tasks. Their compact dimensions—3.7 x 1.5 x 1.5 inches—allow for easy installation in confined spaces without sacrificing strength.

Each connector’s exterior finish is smooth polypropylene, which not only reduces friction during assembly but also minimizes the risk of abrasion against adjacent components. The NPT (National Pipe Thread) male threads conform to industry standards, guaranteeing compatibility with a broad range of existing pipe fittings, valves, and adapters. This universal compatibility simplifies inventory management for maintenance crews and reduces the need for multiple specialized parts.

Usage

These connectors excel in hydraulic and pneumatic systems where reliable fluid transfer is critical. They are commonly employed in irrigation setups, water treatment plants, chemical processing lines, and automotive cooling circuits. The barbed end easily slides onto hoses of matching diameter, while the NPT male thread securely mates with threaded pipe sections, creating a robust joint that can withstand vibration and pressure fluctuations typical of dynamic fluid systems.

Installation is straightforward: simply push the hose onto the barbed side until it reaches the shoulder, then apply thread sealant or PTFE tape to the NPT threads before tightening with a wrench. This simple process reduces installation time and minimizes the potential for installation errors, which can lead to leaks or premature failure. The connectors are also suitable for DIY enthusiasts tackling home improvement projects such as garden hose extensions, outdoor sprinkler repairs, or small‑scale water filtration installations.

Because the connectors are made from non‑corrosive polypropylene, they are ideal for use with aggressive chemicals, including acids, alkalis, and solvents, without degrading the material. This chemical resistance expands their applicability to laboratory environments, cleaning equipment, and industrial processes where fluid purity and equipment longevity are paramount. Additionally, the connectors’ ability to operate at low temperatures makes them a reliable choice for cold‑weather applications such as snow melt systems and refrigerated fluid lines.

FAQ

What hose sizes are compatible with this connector?

The barbed end is sized for 1‑1/2″ (38 mm) inner‑diameter hoses. It works best with hoses that have a matching outer diameter, ensuring a snug fit without the need for additional clamps.

Can I use these connectors with metal pipe threads?

Yes. The NPT male threads conform to standard pipe thread dimensions, allowing you to connect the fitting to metal or plastic NPT‑threaded pipe sections, valves, and adapters without compatibility issues.

Is a thread sealant required for a leak‑free joint?

While the polypropylene material provides a good seal, applying PTFE tape or a suitable thread sealant to the NPT threads is recommended for maximum leak protection, especially in high‑pressure or critical applications.

What is the warranty coverage for this product?

ALKARAMA offers a one‑year limited warranty covering manufacturing defects. If a defect is identified, we will replace the affected connectors at no additional cost, provided the product is used according to the guidelines.

Are these connectors suitable for food‑grade applications?

These particular connectors are not certified for direct food contact. For food‑grade requirements, please select fittings that meet FDA or NSF standards specifically labeled for food handling.
