Thank you for purchasing an Aquaknect Flexible Connector. For best results, please give consideration to the following points when installing this product.

GENERALLY

  1. The installer is responsible for ensuring the integrity of the installation.
  2. This product is not designed for use in inaccessible locations or below ground.
  3. Ensure that threads are clean and sealing surfaces are undamaged on both elements of the fitment.
  4. Ensure the stainless steel braid is not exposed to abrasion or corrosive substances.
  5. Refer to the hose label and tables on page four for the torque required to achieve an effective seal for each end fitting.
  6. Aquaknect Flexible Connectors are not designed to be subjected to tensile or compression stress, particularly in some configurations of expansion joints
  7. Do not twist, kink or stretch hose, and ensure it is not exposed to external stress.
  8. The operating temperature and working pressure ranges vary for each product. Compare the particulars of your installation with pressure and temperature tables to ensure suitability
  9. To avoid subjecting the hose to stresses it was not designed for, compare the particulars of your installation with the details on pages 2 and 3.

PUSH ON CONNECTORS

  1. Ensure that the copper tube is the correct size, cut squarely and externally chamfer to remove any trace of burrs to prevent O-Ring damage.
  2. Ensure that the Push-On fitting is pushed up to the tube stop. Pull the fitting to check that it is held securely. Mains pressure test the system and check fitment.
  3. To remove the fitting: ensure system is de-pressurised; push Collet back against fitting face. With the Collet held in this position the fitting can then be removed from the copper tube.
NOTE: Use only for non coated copper tube. Push on connectors are NOT for use with gas installations.

1. Cut the tube straight. de-burr and chamfer the tube, so as to not damage the O-Ring on application 2. Important - push the tube through to the End-Stop to ensure the O-Ring seal
3. The Tube securely in position 4. Removal - After pressure has been removed, removal of the tube is effected by pressing in the Acetyl collet.


CONNECTOR SPECIFICATION RANGES





NOTE: The above temperatures are allowances for maximum spikes. Continued operation at these
temperatures can affect the life of the connector.
It is recommended that for water a maximum constant operating temperature of 80ºC is provided.
Maximum constant operating temperature for gas Classes B and D is 80ºC and Class C is 60ºC.

HOW TO ORDER FLEXIBLE CONNECTORS


  1. Use designated Code Number, selecting by flexible internal diameter, type of fitting and length required.
  2. If length not shown, always select next code up - DO NOT select lower code number example:-
    1. Standard Length 15mm ID x 400 x ½ F/Cone x ½ F/Cone = Code Number WF0401
    2. Special Length 15mm ID x 450 x ½ F/Cone x ½ F/Cone=Code Number WF0401/450
  3. If fitting combination not shown, please contact Agent or Manufacturer for special pricing.
  4. Length overall (LOA) is the distance from 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 adaptors, which may be supplied with the product.



NOTES:
  • All Fittings unless specifically noted are BSP
  • All F/Flat Seats include Washers
  • Different minimum lengths apply to each diameter. Please contact our National Sales office for details before ordering.


Pressure Loss Calculation

Calculation method to determine loss in a flexible hose (hose + connectors).

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 2).
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

Examples
- 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 Bar
- 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
