Frequently Asked Questions
What makes the spool type "full face"?
The rubber is moulded across the entire flange face, from bore to bolt circle, so it seals the whole surface against the mating flange without a separate gasket — ideal for large, flat-faced connections.
Why is it longer than a sphere joint?
The extra face-to-face length and multi-ply construction let the spool type carry higher pressure and reach larger diameters, while still absorbing axial, lateral and angular movement.
Does a spool type joint need a control unit?
On large-bore and higher-pressure lines the pressure thrust is significant, so a tie-rod control unit is usually recommended to carry that thrust and limit movement, especially where the line is not fully anchored.
What pressures and sizes are available?
The range covers PN10 to PN25 (higher on request) and diameters up to DN3000 and beyond, each combination verified for the specific duty.
Which elastomer should I specify?
EPDM for water and cooling duty, NBR for oil and fuel, NR for abrasive media, and chlorobutyl or CR for chemicals — chosen from the medium and temperature of your line.
Can it handle vacuum or suction?
Yes. Internal steel support rings are fitted where the line sees vacuum or suction lift, preventing the body from collapsing inward.
