A PAIR of angle-pattern, Binder-style, connection adaptors, complete with 3.3mm diameter x 37mm long needles.

These connection adaptors have become the ‘standard’ within the HVAC commissioning industry for several reasons:

  • It is extremely common for valve manufacturers to fit Binder-style pressure-test-points to their balancing valves and a needle diameter of 3.3mm is compatible with the majority of these manufacturers, whilst providing excellent resistance to bending / snapping.
  • A needle length of 37mm ensures that the aperture at the end of the needle enters the waterway, without being adversely affected by any turbulent flow within the main body of the balancing valve.
  • The angle-pattern design provides significant versatility when trying to take readings from target valves in tight spaces.

The insertion probe has a brass body and a stainless steel needle. The knurled ring has a 3/8″ UNF female thread to suit the corresponding male thread on a Binder-style pressure-test-point. Supplied with an O-ring fitted at the base of the needle to assist sealing on the pressure-test-point (effective needle length with O-ring fitted is circa 35.5mm).

The elbow and quick-release plug are nickel-plated brass and the Dowty washer is mild steel with a bonded nitrile seal.

P.T.F.E. thread-sealant is applied to the joint between the insertion probe and the elbow, thus creating a solid seal.

Directly compatible with the quick-release coupling on all Comdronic connection tubes.
