Screwed Braided Flexible Connectors
Product Code: BBT/N
EMFLEX braided flexible connectors are used to suppress vibration from pumps, to absorb intermittent lateral movement in pipelines and to compensate for subsidence when pipelines cross building movement lines. They must be installed at right angles to the direction of movement when installed in pipelines and close to the suction and discharge connections when used on pumps. They are not suitable for absorbing AXIAL movement, but are an alternative to articulated or angular expansion joints for low velocity applications.

Additional Information
For use on steel pipelines, and is suitable for steam and hot water for heating and gas. The unit has a stainless steel hose and over braiding with fixed male BSP taper threads in carbon steel as standard.
For use on copper pipelines, and is suitable for condensate, domestic hot water and gas. This unit has a stainless steel hose and over braiding with fixed male BSP taper threads, also in stainless steel, as standard. This unit is also suitable for portable water, as all internal surfaces are stainless steel.

Working Pressure: 16 bar (1600 kPa).
Test Pressure: 1.5 x Working Pressure.
Working Temperature: 185ºC.
Material Specifications
Convoluted hose and overbraid are stainless steel.
For steel service the threaded ends are carbon steel.
For copper service the threaded ends are stainless steel.
End fittings available:
A wide range of different end fittings are available; please contact us for more information. Please note, however, that the stated overall lengths for a given lateral movement will change with different end fittings. Rotary Unions, Swivel Joints and Quick Release Couplings are available.
Type BBTA and BBTNA
As type BBT and BBTN above but with ‘Armaflex’ insulation applied over the braiding.
Temperature: 105ºC
Design Consideration
The overall lengths in the table are for flexing applications. When using these units on static applications, for example subsidence, they will absorb 1.5 times the lateral movements shown.
For installation details see our design book.
Notice
Braided flexible connectors must not be used to absorb AXIAL compression or elongation.
Do not exceed the minimum bend radius.
Do not stretch or twist the unit.
Type BBTP and BBTNP
As type BBT and BBTN above but with a smooth plastic shrink fit cover applied over the braiding. Available in red, blue, green, yellow, black and white.
Temperature: 90ºC

Reduce the emission of noise and vibrations from your fans, coolers, chillers or other similar types of machinery using our EMFLEX Stainless Steel Flexible Hose. We manufacture and supply braided hoses for nominal sizes between 15mm and 50mm, with larger products available on request. Each product can be manufactured to your specific length requirements.
Our Type BBT flexible hose is manufactured from a stainless steel convoluted hose with a stainless steel overbraid and carbon steel end fittings. The Type BBTN has the same construction, but comes with stainless steel end fittings.
This product comes with standard male end fittings, however a wide variety of end fittings are available on request. We manufacture bespoke products for any system, including rotary unions, swivel joints, quick release couplings and more. Simply complete an enquiry form, and one of our team members will get in touch. With over 40 years of trusted industry experience, the team at Minikins are here to help.
