These NORMAPLAST® SV connectors made of Polyamide 6 have a tapered thread on one end and one or two push-on hose connectors on the other end. The ribbing of the push-on connectors ensures that the hose sits securely.
 
The three available thread geometries are colour coded as follows to allow quick visual identification:

- Metric taper thread: light grey
- Whitworth pipe thread:anthracite
- NPT thread:black

For the threaded connecting pieces the coefficient of expansion of 100 x 10° must be considered if there is any exposure to temperature fluctuations. Our standard materials are classified under the UL (Underwriters Laboratories) system as:

POM : HB( Horizontal Burning)
PA 6 : HB
PP : HB
PA 6.6: HB
PA 12: HB
