Ultra soft twin shield 7800 series

EMI/RFI shielding gasket with low closure force to prevent bending of doors, lids and panels combined with a environmental seal (dust/water seal)

Ultra soft twin shield 7800 series is a range of HF gaskets similar to our Ultra soft shield 7400, which have been combined with an environmental seal (also known as water seal) made of closed-cell foam rubber. The product requires very low closure force. All gaskets are provided with a self-adhesive strip on the side of the water seal.

The standard material for the water seal is neoprene foam. Alternatively a slowly recovering PVC foam is available, which is fully watertight at 30% compression.
