NBRE3

nbre3

The advantages of a premium grade thin wall polyolefin combined with the versatility of a good 3:1 shrink ratio. Also available in a range of sizes up to 39mm diameter, NBRE 3 complies with MIL-1-23053/5 Class 1 and 2*, DEF>STAN 59-97 type 2b*, UL 224*, CSA* specifications.

The NBRE 3 shrink ratio enables fewer sizes to be stocked for a wider range of applications. The added advantage of NBRE 3 availability in a range of colours, makes this versatile tubing ideal for strain relief, protection of terminals and both coding and identification.
