How to order flexible connectors
1. Use designated Code Number, selecting
by flexible internal diameter, type of fitting and length
2. If length is not shown, always select next code
up - DO NOT select lower code number.
a. Standard length
10mm ID x 400 x 1/2"
F/Flat = Code Number WF0174
b. Non Standard
15mm ID x 450 x _F/Cone x _F/Cone = Code Number WF0401/450
3. If fitting combination of end fittings is not shown,
please contact Aquaknect Flexibles A/Asia for special pricing.
4. Overall length is defined as distance from
one fixed fitting to fixed fitting, as shown in the diagram below. The
measurement is not taken from the face of the nuts, nor does it take into
account any adapters which may be supplied with the
Note: All fittings unless specifically noted
are BSP. All female Flat Seats include washers.
No order will be accepted where the Overall length is less than that
indicated in the table below:

As we manufacture in Australia and don’t rely on imports, we are capable of
many variations and adaptions. If you have any special requirements, just ask
one of our helpful staff, or fax us a drawing.
The Aquaknect Flexible range of end fittings is extensive and this catalogue
showcases our core range.

If you are unable to get the best result, please take into consideration the
following points when installing this product.
The installer is responsible for ensuring the integrity of the installation.
This product is not designed for use in inaccessible locations or below
Ensure that threads are clean and sealing surfaces are undamaged on both
elements of the fitment. Ensure the stainless steel braid is not subjected to
abrasion or corrosive agents.
Refer to the hose label for the torque required to achieve an effective seal
for each end connector.
Plumbezy Flexible Connectors are not designed to be subjected to tensile or
compression stress, particularly in some configurations of expansion joints.
Do not twist, kink, or stretch, and ensure that the hose is not exposed to
The operating temperature and working pressure ranges vary for each product.
Compare the particulars of your installation with table on page TTD2 to ensure
To avoid subjecting the hose to stresses it was not designed for, compare the
particulars of your installation with the diagram on page INS3.
Pressure Loss Calculation
Calculation method to determine loss in a flexible hose (hose +
Formula ∆ p = (TxL) + R (in m Bar)
T = Pressure loss in m bar per metre length of hose for each
ID against flow M3/H (Diagram 1)
L = Length of
flexible hose in metres
R = Pressure loss across 2 straight
connectors (Male/Female). Under same conditions as T (diagram
For a flexible hose incorporating 1 straight connector and
elbow: R value x 1.5
For a flexible hose incorporating 2
elbows: R value x 3
- Flexible hose, ID 15mm, Length 0.5m
Male/Female Flow = 1,000 L/H,
∆ p = (21m Bar/m x 0.5m) + 17 m Bar = 27.5m
- Flexible hose, ID 20mm, Length 0.8m Male/Female Flow = 1,000 L/H,
p = (2.6m Bar/m x 0.8m) + (2m Bar x 1.5m) = 5.08m Bar
