Tied Rubber Bellows - Type JP06JP03 Rubber Bellow

High Temperature Water.

Now Available With Precision Flt Flexible Lagging Jackets To Suit JP05


Tied E.P.D.M. rubber bellows with high tensile cord reinforced body and steel reinforced collar. Fitted with zinc plated carbon steel oval flanges complete with fully threaded tie bars and rubber top hat washers. Drilled to BS. 4504 NP16.


Stourflex tied rubber bellows are designed to accommodate misalignment and lateral movement. They are also used to reduce noise and vibration from pumps and reciprocating machinery. The high tensile cord reinforced body allows the JP06 to be used on heating systems and engine cooling applications or where extended service life is required.

Maximum working temperature 105ºC. (Intermittent peaks up to 120°C) Maximum working pressure 16 Bar. Maximum working pressure at 105°C = 6 Bar Maxiumum working pressure at 90°C - 10 Bar.

Stourflex rubber bellows should not be used at both their maximum working temperature and pressure respectively. Maximum test pressure = 1.5 x working pressure or 1.5 x flange rating, whichever the lower.


Stourflex are now able to offer a tailor-made flexible lagging jacket to help reduce heat losses on LTHW systems and heat gains & condensation on CHW systems. Please ask for more information.
