Class 125 Bushings

Class 125 bushings are a subclass of Schedule 40 PVC pipe fittings used to connect two plumbing components of different diameters. The bushings are classified as Class 125 fittings to indicate their maximum 125 PSI pressure rating suitable for low to medium pressure applications. They are primarily fitted and installed in plumbing and irrigation systems. Class 125 bushings are used to reduce the size of a PVC pipe or fitting connection to transition a larger or smaller diameter pipe. PVC bushings have a spigot end that fits into the socket end of a larger pipe and a socket end that fits over a smaller pipe. This design creates a secure, leak free connection between pipes of different sizes. Class 125 bushings are an economical, budget friendly solution to change pipe sizes. They allow system design flexibility and adaptability to various system requirements without the need for complex or multiple fittings. Class 125 bushings are made identically to Schedule 40 PVC but without final testing to save production costs to create a cost effective alternative. Overall, Class 125 PVC bushings should provide the same performance as Schedule 40 fittings, although this cannot be guaranteed as post-production testing has not been performed. 

**Notice** Class 125 bushings are not suitable for pressurized liquid applications to exceed 125 PSI or use in systems that require certified Schedule 40 PVC as per building or plumbing codes. They are not intended for use in pressurized air applications.

Class 125 bushings are available in reducer sizes from 10ʺ x 3ʺ to 10ʺ x 8ʺ in diameter. Class 125 reducer bushings are manufactured to Schedule 40 thickness and dimension standards. Class 125 bushings come with spigot by socket ends for insertion and slip on connection and solvent weld installation with PVC primer and cement. 

Class 125 bushings are USA made by Westlake Pipe & Fittings®, previously LASCO Fittings®, one of America’s top trusted manufacturers of PVC pipework. Class 125 PVC bushings are made from rigid, professional grade polyvinyl chloride (PVC) specifically formulated to meet ASTM D1784 standards for quality, product consistency, and reliable performance. Class 125 bushings are rated for pressures up to 125 PSI, heat rated for temperatures up to 140°F (60°C), and compatible with traditional Schedule 40 PVC pipe and components. The reducer bushings are manufactured in an NSF certified facility using modern methods and high purity materials free of harmful additives or chemicals.

Class 125 reducer bushings are precision engineered and professionally manufactured to seamlessly connect pipes of differing diameters to ensure optimal flow rates and pressure management in plumbing systems for various applications. Class 125 PVC material is known for its durability, chemical compatibility, corrosion resistance, temperature stability, and lightweight properties. The fittings are low weight, easy to handle, and offer straightforward installation. Their PVC corrosion resistance is suitable for underground installation and use in plumbing various chemicals and solutions compared to alternatives. Class 125 bushings are designed with smooth pipe walls to minimize friction, flow drag, and reduce the potential biofilm or sediment buildup that can cause clogs or impact system quality.

Their PVC construction provides good impact strength, low thermal conductivity, and corrosion resistance that makes them a reliable choice for long term use in plumbing systems. They are lightweight for easier handling and installation compared to metal or other heavy materials. 

• PVC Material: Long lasting, stable plastic resistant to impact, chemicals, and corrosion
• Durable Construction: Resistant to environmental and underground corrosion
• Large Sizes: Large diameter fittings for high volume plumbing applications
• Pressure Rated: Can handle pressures up to 125 PSI
• Size Transition: Allows connections between two different sized PVC pipes
• Cost Effective: Economical compared to traditional Schedule 40 or metal pipe fittings
• Leakproof: Leak free connections when properly installed
• Easy to Install: Lightweight, socket connection for easy handling and installation

Class 125 bushings can be used wherever Schedule 40 PVC pipe and fittings can be used and where building and plumbing codes allow their use. They are engineered for large diameter, high volume, low to medium pressure plumbing systems. Class 125 bushings are a cost effective alternative for Sch 40 plumbing systems used in residential, commercial, agriculture, and industrial applications. Common uses for Class 125 PVC bushings include potable and nonpotable water distribution, large scale irrigation, wastewater handling and treatment, industrial and manufacturing activities, and chemical processing.
