Nylon Gland Sealing Washer
Nylon Gland Sealing Washers (also specified as cable gland gaskets or flat sealing rings) provide reliable secondary static sealing between cable gland male threads and enclosure entry ports. Designed to maintain continuous compressive stress against environmental elements, these virgin PA66 washers ensure dust-tight and watertight integrity in industrial electrical installations.

Nylon Gland Sealing Washers (also specified as cable gland gaskets or flat sealing rings) provide reliable secondary static sealing between cable gland male threads and enclosure entry ports. Designed to maintain continuous compressive stress against environmental elements, these virgin PA66 washers ensure dust-tight and watertight integrity in industrial electrical installations.
Key Features
Virgin Polymer Structure: Molded exclusively from high-grade Polyamide 6.6 (PA66) resin, delivering optimal tensile strength and resistance to ambient fatigue.
Balanced Force Distribution: Precision-cut flat geometry spreads clamping torque evenly, preventing localized deformation or point-stress fracturing on panel walls.
Enclosure Ingress Protection: Complements O-ring or standard cable entries to sustain system protection ratings up to IP68 when properly torqued against flat surfaces.
Wide Thermal Range: Maintains mechanical and sealing performance across continuous operating temperatures from -40°C to +100°C (short-term tolerance up to +120°C).

Manufacturing & Quality Control
Incoming Resin Verification: Raw PA66 batches undergo Melt Flow Index (MFI) and moisture content analysis prior to processing.
Dimensional Inspection: Automated optical sorting and periodic profile projector checks maintain strict ID, OD, and thickness tolerances (+/-0.1 mm).
Lot Traceability: Master cartons feature permanent batch labeling linked to downloadable Material Test Reports (MTR) and compliance documentation.
Frequently Asked Questions
Q: How do I select the proper washer size for my cable gland?
A: Match the inner diameter (ID) of the washer directly to the nominal thread size of the cable gland (e.g., an M20 x 1.5 gland requires an M20 washer). Ensure the outer diameter (OD) provides full coverage over the enclosure knockout hole.
Q: Can standard natural white washers be used outdoors?
A: Standard natural PA66 lacks UV stabilizers and may embrittle under direct sunlight over extended periods. For outdoor applications, specify UV-stabilized black PA66.
Q: What is the continuous operating temperature range?
A: Standard PA66 material maintains structural stability and sealing elasticity from -40°C to +100°C.
Q: Are test reports and compliance certificates provided?
A: Yes. RoHS, REACH declarations and Material Test Reports (MTR) are available upon request for every production batch.
Q: What is the standard minimum order quantity (MOQ)?
A: Stock standard sizes start at an MOQ of 1,000 pieces per SKU. Custom tooling or non-standard dimensions are subject to evaluation.
Q: What are the standard production lead times?
A: In-stock standard configurations ship within 3 to 5 business days. Custom molded specifications typically require 15 to 20 business days.
