They are co-moulded and elastomer parts that function as liquid tight plugs with an IP 67/68 rating, yet can be pierced by round wire, cable or tubing to function as liquid tight bushings with the same resulting IP 67/68 rating.
Once pierced, the liquid tight bushing converts raw edged holes to smooth, neat, insulated holes. When used as a liquid tight bushing, the HEYCo-molded Liquid Tight Break-Thru Plug insulates and mechanically protects electrical and telecommunications cable, tubing, hose, rope and utility lines.
- HEYCo-molded Liquid Tight Break-Thru Plugs have locking fingers that snap easily into holes with only fingertip pressure in fractional increments up to the maximum panel thickness.
- These plugs withstand a push back force of greater than 35 pounds and are available in multiple sizes for use in .500" (12.7mm) to 1.093" (27.8mm).
- They are for use in panels as thin as .020" (0.5mm) and as thick as .063" (1.6mm). Heyco will be developing parts for thicker panels in the near future.
- HEYCo-molded Liquid Tight Break-Thru Plugs are made from Nylon 6/6 and TPE, are IP 67/68, have an HB flammability rating and have a temperature rating of -40°F (40°C) to 212°F (100°C).
