Thermal bending 45 degrees

Therm bend with 20 mm grey Neopor® insulation shell.

Neopor® has a high insulation value, approximately 15% better than the previous therm bends with white Flamingo® shell.

The inner bend is made of high impact polystyrene (HIPS). It has a socket end and a spigot end. If you need a 90° bend, it is very easy to make it by connecting 2 45° bends together.

Used in conjunction with Duka therm pipes. Always remember to seal joints with glue or tape.
