About the 1330353010 SES Sterling Membrane Grommet
Part 1330353010 (listed by distributors as 01330353010) is a DG-series membrane grommet from SES-STERLING, moulded in black polyvinyl chloride. It fits a 20 mm panel hole and blanks the opening until the membrane is pierced, after which it passes a cable of up to 13.5 mm diameter per RS Components’ listing. The grommet suits panel thicknesses up to about 2 mm and is rated for operating temperatures from −30 °C to +70 °C; the material is described as ageing-resistant and oil/fuel stabilised. BOLTON’s quotation record confirms the 20 mm panel-hole size and PVC material. Membrane grommets of this type protect cable insulation from chafing on cut panel edges and keep unused openings closed on enclosures and cabinets.
