Cable gland BITNER D/M-16x1.5 IP68 — M16 x 1.5 thread, waterproof cable entry

BITNER D/M-16x1.5 is a cable gland with an M16 x 1.5 thread designed for waterproof cable entry in electrical enclosures. With an IP68 protection rating, this gland ensures reliable sealing against dust and temporary submersion while providing mechanical strain relief for cables routed into junction boxes, control cabinets and outdoor equipment. The threaded design enables secure fastening to panels and housings with compatible M16 x 1.5 ports.

Advantages

The IP68 rating provides protection against dust ingress and temporary immersion, making the gland suitable for harsh environments. Its threaded M16 x 1.5 interface delivers a tight mechanical connection to panels and enclosures, reducing the risk of water or contaminant entry. Built to provide strain relief, the gland helps maintain cable integrity and connection reliability over time. The compact M16 size allows use where space is limited while still accommodating a range of cable diameters compatible with the gland's sealing element.

Suitable for

• Sealing single cables entering junction boxes and electrical enclosures
• Outdoor electrical installations exposed to moisture and dust
• Marine and coastal equipment where temporary submersion may occur
• Industrial machinery and control cabinets requiring threaded waterproof entries

Key specifications

• Thread type and size: M16 x 1.5 thread for panel mounting
• Ingress protection: IP68 (dust-tight and temporary immersion resistant)
• Function: waterproof cable entry with strain relief
• Application environment: indoor, outdoor, industrial and marine use
• Form factor: compact, low-profile gland suitable for limited-space installations

How to use

Install the gland by inserting the threaded portion through a prepared M16 x 1.5 hole in the panel or enclosure, then tighten the securing nut on the inside or use the integrated thread depending on the variant. Pass the cable through the gland and position the internal sealing element around the cable sheath. Tighten the cap or compression nut to compress the seal evenly and provide strain relief. Verify the seal by checking for proper compression and ensuring no gaps remain around the cable entry. For installations subject to submersion, confirm that the enclosure lid and other penetrations also meet required IP ratings.

Usage recommendations

Choose a gland variant whose sealing range matches the cable outer diameter to ensure effective waterproofing and strain relief. Avoid over-tightening which can deform the sealing element; tighten until the seal compresses uniformly. Inspect seals periodically in harsh environments and replace the gland if the sealing material shows signs of wear or degradation.
