Class 125 Tees

Class 125 tees are specialized pipe fittings used to join three sections of PVC pipe at a 90 degree angle to form a T-shaped junction. They are part of the Class 125 category of Schedule 40 fittings and can handle pressures up to 125 PSI. Class 125 PVC tee fittings are large diameter pipe fittings used in high volume, lower pressure plumbing systems. The fittings provide a reliable means of distributing or combining liquid media flow from three directions. Class 125 PVC tees are designed to create secure connections between three pipes and allow fluid to flow through the fitting from one pipe to another. The fittings’ engineering and pressure rating makes them suitable for various low-to-medium pressure applications. They are common in residential and commercial plumbing, irrigation systems, and industrial applications. Class 125 tees are manufactured identically to standard Schedule 40 fittings but have not been tested to ensure pressure performance which saves costs for a lower purchase price. Overall, Class 125 tee fittings should provide the same performance as Schedule 40 fittings, although this cannot be guaranteed due to the absence of post-production testing. 

**Notice** Class 125 tees are not suitable for pressurized liquid applications exceeding 125 PSI or systems requiring certified Schedule 40 PVC as per building or plumbing codes. They are not intended for use in pressurized air applications.

Class 125 tees come in 10ʺ and 12ʺ sizes in Schedule 40 sizing standard. Class 125 reducing tees are available in 4ʺ, 6ʺ, 8ʺ and 10ʺ sizes for plumbing projects that require connections between different sized pipe or components. The fittings come with plain end slip socket connections for solvent weld installation with PVC primer and cement. 

Class 125 PVC tees are USA made by Westlake Pipe & Fittings®, previously LASCO Fittings®, one of America’s top trusted manufacturers of PVC pipework. The fittings are manufactured from premium grade PVC thermoplastic that meets ASTM D1784 requirements. PVC material provides a long service life, dependable performance, application versatility, corrosion resistance against various chemicals, underground soil conditions, and rust. Class 125 fittings are pressure rated for liquid plumbing systems up to 125 PSI and heat rated for temperatures up to 140°F (60°C). They are manufactured on the same production line as standard Schedule 40 fittings and can be used with Schedule 40 components. Class 125 tees are made in an NSF certified facility and from material free of harmful chemicals or additives.

Class 125 tees are engineered and manufactured for reliable, long term service. Their professional, premium PVC construction and design delivers high impact strength, low thermal conductivity, corrosion resistance, low weight, and smooth internal surfaces. The lightweight design makes handling and installation easy compared to metal alternatives. The smooth pipe walls help prevent biofilm buildup and sediment accumulation that can lead to clogs so the system remains operational. These properties make Class 125 PVC tees a dependable option for lasting performance. 

• 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
• Three Way Branching: Creates 90° three way plumbing connections
• 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 tees are used in various applications in residential, commercial, and industrial systems for high volume, low pressure fluid conveyance. They are a cost effective alternative to Schedule 40 components in plumbing projects where building codes or projects allow for their use. Common applications and uses for Class 125 tees include potable and non potable water distribution, agricultural irrigation systems, chemical processing pipelines, wastewater treatment infrastructure, fertilization delivery systems, and distributing liquid materials in industrial settings.
