Functionality and types of compression tees
The compression tee is a cornerstone fitting in pressurized distribution, branching a main stream into two directions or taking off a 90-degree lateral. It is produced in equal configurations (identical diameter on all three ports) and reducing formats (smaller central branch relative to the run). The reducing version eliminates separate downstream adapters, maintaining compact manifold geometry.
In alignment with ISO 17885 provisions, the engineered body evenly distributes multi-directional hydraulic thrust. The virgin polypropylene compound prevents biological scaling and chemical corrosion when conveying saline groundwater or dissolved agrochemical formulations.
Dimensional parameters and execution guidelines
Compression tees are typically available in outside diameters from 20 to 125 mm rated at PN10 working pressure. In reducing models, branch outlet diameters (od2_mm) range from 20 to 110 mm, catering directly to line step-downs without additional adapters.
During assembly, axial pipe alignment across all three ports and thorough end deburring are essential to seat seals properly without rolling. Nuts should be hand-threaded first, then tightened firmly with a strap wrench. Submit your run and branch diameters via the quote form to obtain official pricing.

Compression Tee (Equal & Reducing) — FAQ
What is the distinction between an equal and a reducing compression tee?
An equal tee features identical diameters across all three ports, whereas a reducing tee has a smaller diameter on the 90-degree takeoff port.
Across what diameter span are compression tees produced?
These tees are generally supplied from 20 to 125 mm outside diameter to handle diverse mainline and lateral requirements.
Can heavy metal pipe wrenches be used to tighten compression nuts?
Specialized plastic or strap wrenches are strongly recommended to tighten fittings without gouging the outer polypropylene nut ridges.
Can compression tees be directly buried in soil?
Yes, high-grade polypropylene and corrosion-proof elastomeric components demonstrate exceptional durability in direct-buried ground.
