The Press Straight Compression Adapter – U Profile is a heavy-duty transition fitting designed to join Multi-Layer Composite Pipe (MLCP) directly to standard copper compression fittings. Ideal for connecting underfloor heating and heat pump lines to main manifold setups, it provides a secure, permanent, and flame-free joint.

Engineered for use with standard U-profile press jaws, the fitting features a premium stainless steel crimp sleeve with a leak-free double O-ring seal. The opposite end provides a secure compression connection, allowing installers to bridge different pipe systems quickly without the need for soldering or specialist transition adapters.

Key Features & Benefits

  • MLCP to Compression: Seamlessly transitions multi-layer composite pipe to traditional compression networks.

  • U-Profile Compatible: Specially designed for precise mechanical sealing using standard U-profile crimping tools.

  • Double O-Ring Seal: Engineered with heavy-duty hydraulic seals for maximum leak prevention and pressure resistance.

  • No Heat Required: Delivers a permanent, watertight joint entirely cold—eliminating the need for soldering or welding.

  • Robust Brass Body: Premium nickel-plated brass construction designed to withstand high operational temperatures and pressures.
