Underfloor Heating Manifold Pipe Coupling — Brass PEX / PERT, 16 mm & 20 mm to 3/4" Outlet

Precision brass manifold coupling for hydronic underfloor heating systems. Adapts Φ16 mm or Φ20 mm PEX / PERT supply lines to standard 3/4" manifold outlets for a secure, leak-resistant connection. Ideal for new installs and service replacements where reliability, chemical cleanliness, and flow efficiency matter.

Solid Brass Body: Excellent pressure/temperature performance and long service life.
PEX / PERT Ready: Optimized sealing geometry for flexible polymer tubing.
Leak-Tight Sealing: Machined seats and threads support reliable, repeatable assemblies.
Corrosion Resistance: Brass resists dezincification and scale in closed hydronic loops.
Clean Composition: Declared no high-concern chemicals for system safety.

Applications

  • Connecting PEX / PERT circuits to 3/4" underfloor heating manifolds.
  • Retrofit and maintenance work where couplings require durable, leak-free performance.
  • Residential and light-commercial hydronic radiant heating systems.

Ordering Options

  • Φ16 mm → 3/4" Manifold Outlet
  • Φ20 mm → 3/4" Manifold Outlet

FAQs

Is this compatible with both PEX and PERT?

Yes. The coupling is specified for either PEX or PERT tubing in 16 mm or 20 mm sizes.

What manifold outlet size does it fit?

Standard 3/4" underfloor heating manifold outlets.

Does it ship with seals or O-rings?

Sealing method depends on your manifold/tube system (compression or O-ring). Use manufacturer-approved seals for your manifold brand.

Temperature and pressure suitability?

Brass couplings are typical for closed hydronic loops. Follow your system’s rated limits and local code; tighten to torque guidance to avoid damage.

Any restricted chemicals?

The listing declares No High-Concern Chemicals.

Can I mix 16 mm and 20 mm circuits on the same manifold?

Yes—use the correct coupling for each loop size and balance flows at the manifold.
