Stainless Steel Double Press-Fit Fittings Equal Tee

Category Tag
  • Efficient Three-Way Distribution: Designed to split or combine flow in a T-shaped configuration with minimal pressure drop, ideal for creating branch lines.
  • Core of the Double Press System: The quintessential fitting in our reliable O-ring sealed press-fit system, engineered for speed and durability.
  • Reliable O-Ring Seal: Utilizes a precision EPDM or NBR O-ring (per GB/T19228.3) compressed during pressing, creating a robust, leak-proof seal resistant to vibration.
  • Certified Performance & Safety: Each fitting undergoes individual pressure testing (>1.05 MPa) and complies with GB/T 19228, ISO 15835, and other international standards.
  • Robust & Durable Construction: Made from 304/316L stainless steel, ensuring corrosion resistance and a long service life in potable water, heating, and other fluid systems.

Precision Branching with Proven Press-Fit Reliability

The Stainless Steel Double Press-Fit Equal Tee is engineered for creating flawless 90-degree branch connections within a piping network. As a central component of our high-performance [Internal Link: Double Press-Fit System Overview], this tee delivers the perfect balance of installation speed, proven reliability, and system integrity for commercial and industrial applications.

 

Engineered for Sealing Confidence: The Double-Press Mechanism

This tee exemplifies the simplicity and effectiveness of the mechanical O-ring seal. The process involves two calibrated presses:

  • First Press: Secures the fitting onto the pipe, initiating O-ring compression.

  • Second Press: Completes the full compression cycle, ensuring the O-ring is uniformly seated to its design depth, creating a gas-tight and liquid-tight seal. This dual-action guarantees consistency that manual methods cannot match.

The integrated EPDM/NBR O-ring provides excellent elasticity and chemical resistance, forming a seal that accommodates minor thermal expansion and contraction, a key advantage detailed in our Double Press System Performance & Testing Data.

The Seal in Section: This view reveals how the precision O-ring is compressed within its groove during the double-press process to form a resilient, long-lasting seal at all three outlets.

Built to Withstand Pressure: Material & Compliance

  • Material: Manufactured from premium 304, 304L, 316, or 316L stainless steel, offering superior corrosion resistance.

  • Standards: Fully conforms to GB/T 19228.1-2011, ISO 15835, EN 10312, and AS/NZS 4128, ensuring global project compatibility.

  • Rigorous Testing: Every single fitting is factory-tested above 1.05 MPa. The system undergoes rigorous 14-hour, 2.5 MPa pressure tests, validating the exceptional pull-out and burst strength of the connection.
