4 inch ADS Corrugated Snap Lock Tee

4 inch ADS Snap-Lok Corrugated Tee – Engineered for Secure Inline Branching

The 4 inch ADS Corrugated Snap-Lok Tee is a molded plastic fitting designed for use in gravity-flow stormwater and subsurface drainage systems. Manufactured from durable, high-density polyethylene (HDPE), this tee provides a dependable branch connection point within 4 inch corrugated pipe networks using a friction-locking Snap-Lok interface.

Its form-matched corrugations ensure structural consistency and compatibility with industry-standard dual-wall or single-wall corrugated pipe systems, supporting reliable performance in site drainage, agricultural, and light commercial installations.

Contractor-Focused Benefits

• ✅ Snap-Lok Coupling – Integral latching mechanism enables quick, tool-free connections without the need for banding or sealant in non-pressurized systems.
• ✅ Impact-Resistant HDPE – Provides high strength-to-weight ratio, excellent chemical resistance, and long-term durability in buried and exposed conditions.
• ✅ Formed Corrugation Match – Interfaces seamlessly with 4 inch corrugated pipe to maintain structural and hydraulic continuity.
• ✅ Non-Clogging Tee Profile – Designed to preserve flow characteristics and minimize debris retention at junction points.
• ✅ ASTM Conformance – Manufactured to meet dimensional and performance standards for stormwater fittings and agricultural drain systems.

Specifications

• Material: High-density polyethylene (HDPE), black
• Size: 4 inch (mainline and branch)
• Connection Type: Snap-Lok corrugated press-fit
• Application: Non-pressure stormwater and drainage systems
• Standards: Conforms to ASTM F667 and AASHTO M252 for corrugated polyethylene drainage fittings

Typical Applications

Primarily used in subsurface drainage systems, including foundation perimeter drains, landscape runoff collection, downspout diversion, and agricultural field drainage. The tee facilitates inline connections where a lateral branch is required off a mainline without compromising flow direction or capacity.

Material & Use Insight

HDPE corrugated fittings are known for their lightweight design and flexibility under load, offering advantages in projects where soil shifting or settling is expected. The Snap-Lok design reduces labor time and supports easy alignment in the field.

The 4 inch ADS Snap-Lok Corrugated Tee provides a field-proven connection solution for efficient drainage layout design. With durable construction and tool-free assembly, it supports consistent performance across a range of site conditions and installation methods.
