3/4 inch PEX Polyalloy Insert Tee Crimp x Crimp x Crimp

3/4" Viega PEX Crimp Tee – PolyAlloy Construction for Long-Term Reliability

The 3/4" Viega PEX Crimp Tee is designed for creating dependable branch connections in potable water or hydronic heating systems using cross-linked polyethylene (PEX) tubing. Made from durable polyalloy, this tee offers excellent dimensional stability, resistance to corrosion, and high tolerance to pressure and temperature fluctuations, making it a preferred solution for demanding residential and commercial applications.

Key Features

• ✅ Material: Polyphenylsulfone (PPSU) polyalloy construction for corrosion and chemical resistance
• ✅ Connection Type: ASTM F1807 Crimp x Crimp x Crimp – compatible with copper crimp rings and stainless steel clamps
• ✅ Size: 3/4" nominal diameter on all three ends
• ✅ Lead-Free: Certified to NSF/ANSI 61 and 372 for use in potable water systems
• ✅ Pressure Rating: Rated up to 200 psi at 73°F

Installation Requirements

Installation requires PEX crimp or clamp tools and a properly sized ring or clamp system. Ensure cuts on PEX tubing are square and burr-free. For reliable joints, follow ASTM F1807 installation guidelines and verify crimp integrity with a go/no-go gauge.

Typical Applications

• • Potable water distribution in residential and multi-family construction
• • Closed-loop hydronic heating systems
• • Radiant heating manifolds and branch lines

Did You Know?

Polyalloy (PPSU) fittings provide superior resistance to dezincification, making them a preferred alternative to traditional brass in chemically aggressive or high-chlorine water conditions.

The 3/4" Viega PEX Crimp Tee delivers the strength, precision, and code-compliant performance that modern plumbing systems demand. With rugged polyalloy construction and easy integration into standard PEX installations, this fitting offers contractors a reliable solution that holds up under pressure.
