More Information:

The Smith-Blair 317 Service Saddle with Double Stainless Steel Straps is a premium component used in water distribution systems, particularly for tapping and connecting new service lines to existing pipelines. Designed for longevity and reliability, it is crafted from durable materials to handle the pressures and demands of municipal, industrial, and commercial water systems.One of the standout features of the Smith-Blair 317 Service Saddle is its use of double stainless steel straps. These straps provide a secure and corrosion-resistant attachment to the pipe, ensuring that the saddle remains tightly in place even under high-pressure conditions. The stainless steel material is particularly resistant to rust and corrosion, making it ideal for use in various environments, including harsh and corrosive water systems.

The body of the saddle is typically made from a ductile iron casting, which offers superior strength while maintaining some flexibility to fit a wide range of pipe diameters. The straps are adjustable and versatile, allowing the saddle to fit securely around different types of pipe materials, such as steel, ductile iron, and PVC.

In addition to its structural durability, the Smith-Blair 317 includes a gasket made of high-quality rubber, often NBR (Nitrile Butadiene Rubber), to provide a leak-free seal. This ensures that the connection between the service line and the main pipe is both watertight and long-lasting, reducing the risk of water loss or contamination.

The Smith-Blair 317 Service Saddle is designed for easy installation. The saddle is simply wrapped around the main pipe, and the double stainless steel straps are tightened securely. This product is frequently used by municipalities and contractors because of its reputation for reliability, ease of use, and resistance to environmental factors. Overall, the 317 is a trusted choice for expanding water service lines without compromising system integrity.
