Good product.

The 1/2" threads are not even close to 1/2" NPT spec. They are impossible to seal.

I needed a manifold for my HF Blast Cabinet to make it easier to add additional items like a blow gun for post cleaning and other accessories. All threads were clean and burr free. It's a good value for me.

These are sold in pairs and they are a good value. The threads were proper taper thread in all holes, and they sealed up well. I work in an Aerospace machine shop, so I have an eye for the quality of machined hardware. The threads were a little rough, like maybe they were using dull tooling. There were some burrs too, but nothing major. They worked and sealed up fine. These were just what I was looking for to do an air delivery system in my shop.

The GASHER 1PCS Aluminum 4 Way 6 Port Pneumatic Manifold Air Distribution Block Splitter is a durable and efficient solution for distributing compressed air to multiple outputs. Designed for use in pneumatic systems, it is commonly used in industrial, automotive, and DIY applications. Here’s a detailed review based on its features and performance:Features & Specifications:Material: The manifold is made from high-quality aluminum, which ensures both lightweight construction and durability. Aluminum is resistant to corrosion, making it ideal for long-term use in demanding environments.Port Configuration: The 4-way 6-port design features one input port and four output ports, with 1/4" output ports. This makes it suitable for distributing air to multiple devices or tools from a single air supply source.Size and Compatibility: The manifold is designed to work with 1/4" NPT fittings, which is a standard size in many pneumatic systems, making it compatible with a wide range of air tools, compressors, and accessories.Versatile Application: This manifold is commonly used in air distribution systems for various purposes, including:Connecting multiple air tools.Pneumatic automation systems.Workshop or automotive air setups.Easy Installation: The manifold’s simple design allows for quick and easy installation in pneumatic systems. It can be mounted directly into the air supply line or connected to other pneumatic components.Pros:Durable Construction: The aluminum material provides both strength and resistance to rust or corrosion, making it suitable for use in various environments, including moist or outdoor settings.Compact and Lightweight: The manifold is lightweight, reducing the overall weight of your pneumatic system, which is especially beneficial when working with multiple components.Efficient Air Distribution: The 4-way, 6-port design allows for effective distribution of compressed air, enabling you to run multiple tools or devices from a single air supply.Standard 1/4" Ports: The 1/4" output ports are a common size in many air tools and compressors, ensuring compatibility with a wide range of equipment without needing adapters.Cost-Effective: Given its quality and functionality, the GASHER manifold is an affordable solution for users looking to distribute air efficiently in their pneumatic systems.Cons:Limited Number of Output Ports: With only 4 output ports, the manifold may not be suitable for users who require a larger number of connections for more complex pneumatic setups. For larger systems, you may need a manifold with more ports or multiple manifolds.Size: While the compact size is an advantage in many cases, it may be too small for users needing a manifold with larger ports or higher air flow for more demanding applications.No Flow Control: This manifold does not include individual flow control for each port. Users who need precise control over the air flow to each output will need additional flow control valves or other adjustments to their system.Conclusion:The GASHER 1PCS Aluminum 4 Way 6 Port Pneumatic Manifold Air Distribution Block Splitter is a solid and cost-effective choice for distributing compressed air in a variety of pneumatic systems. Its durable aluminum construction, lightweight design, and 1/4" NPT output ports make it a practical option for small to medium-scale air distribution needs. While it offers good value for those needing to distribute air to multiple devices, it may not be the best fit for users requiring a larger number of output ports or precise flow control. For most DIY, workshop, or small industrial applications, the GASHER manifold provides an efficient and reliable solution at an affordable price point.
