This groove-mounted gasket combines Spira-Shield’s EMI shielding (86-165dB) with a bulbous silicone seal for environmental protection. Available in standard (~33 lbs/inch) and moderate (~13 lbs/inch) force options, it features tin/lead-plated beryllium copper spiral and 40-60 durometer silicone. Ideal for space-constrained applications requiring both EMI shielding and environmental sealing in groove-mount configurations.
