The Gel sel closure supplied by Telsto Development Co., Limited is a weatherproof sealing device for fibre-optic cables and splices used in outdoor and underground telecom installations. It incorporates a silicone gel and polymer heat-shrink composite that provides an IP68 rating, meaning the unit is dust-tight and can be submerged in water. The closure supports multiple splice configurations and is designed for long-term protection against moisture, dust and environmental stress. Telsto lists the product as suitable for FTTH, backbone and access network deployments.
Silicone gel technology is common in the telecom sealing market because it retains flexibility while resisting temperature extremes. Typical industry units operate between -40°C and +85°C and accommodate cable diameters from 2 mm to 12 mm, which matches the range covered by most Telsto closures. Standard packaging is a bulk carton holding twenty units, each weighing around 120 g, facilitating efficient freight handling. The composite construction also meets IEC 60529 standards for ingress protection, a benchmark many network operators require.
Network operators, internet service providers and infrastructure contractors purchase these closures to safeguard splice points in fibre-to-the-home and backbone projects. Telsto offers the product with flexible trade terms, including FOB and CIF options, and accepts low minimum order quantities typical for specialised telecom components. Importers should confirm the exact packaging details, certification documents and any required customs paperwork with the supplier before placing an order.

Before placing an order with Telsto Development Co., Limited, importers should verify the IP68 rating and the silicone-gel composition against the supplier’s technical data sheet. Request a sample to confirm the sealing length of 150 mm and the compatibility with the intended cable diameters. It is also advisable to obtain any IEC 60529 compliance certificates and to confirm the exact bulk-carton packaging configuration that will be used for shipment.
Telsto lists flexible trade options such as FOB and CIF, but the exact Incoterm should be agreed in writing before production. Because the response rate is recorded as 0 %, buyers need to establish reliable communication channels and confirm payment terms, typically a letter of credit or advance payment. Shipping from Shanghai allows access to major ports, so discuss container loading plans and any required export documentation early in the process.
Arrange a third-party inspection to check the gel seal’s integrity, IP rating and dimensional tolerances before the cartons are sealed. Request the supplier’s test reports for moisture resistance and IEC 60529 compliance, and ensure they are issued by an accredited laboratory. Retain copies of the commercial invoice, packing list and certificate of origin to smooth customs clearance when the goods arrive in the destination country.
