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.
