Cable Gland Product Range
PG Plastic Cable Glands
PP plastic cable glands with PG threads, listed from PG7 to PG63. White and black styles are shown in the catalog; confirm colour, sealing insert and fit for the selected model.
Metric Plastic Cable Glands
Metric PP plastic models from M12 x 1.5 to M63 x 1.5. Compare cable entry bore, spanner size, overall height, thread length and locknut thickness.
PG Nickel-Plated Brass Cable Glands
Metal PG7 to PG63 options with listed cable ranges from 3-6.5mm to 42-52mm across the series. Confirm the chosen range and enclosure interface.
Metric Nickel-Plated Brass Cable Glands
Metric metal entries from M8 through M63, including two M25 x 1.5 cable-range options. Select by the exact cable diameter, pitch and mounting dimensions.
G Thread Metal Cable Glands
G1/2 to G3 options with the cable ranges and mounting dimensions shown in the table. Match the exact G thread and sealing arrangement to the enclosure.
NPT Metal Cable Glands
NPT1/2 to NPT3 options for a specified NPT entry. Compare the catalog cable range and dimensions, then confirm the approved thread and installation drawing.
Cable Gland Applications
Match the cable gland to the cable jacket, enclosure entry and operating environment. Evaluate the complete installed cable-entry system against the requirements of the equipment.
Control Panels & Distribution Enclosures
Secure cables where they enter switchboards, control cabinets and distribution boxes. Review entry thread, enclosure wall thickness, cable diameter, sealing components and access for tightening. Select any required ingress-protection evidence for the complete installation.
Machinery & Equipment Junction Boxes
Organize cable entries into machinery, junction boxes and instrument housings. Select plastic or metal construction around mechanical exposure, jacket compatibility, service conditions and required retention. Protect cables from sharp edges and follow the approved installation instructions.
Lighting & Outdoor Electrical Equipment
Review cable-entry options for lighting controls and suitable outdoor electrical housings. Confirm temperature, UV, moisture, corrosion and enclosure sealing requirements for the chosen gland and cable; appearance alone does not establish an outdoor or submersion rating.

The metric metal table retains both M25 x 1.5 variants: 12-16mm and 13-18mm cable ranges. M8 is printed as M8 x 1.0 (1.25) in the catalog; confirm the required pitch. Slash-separated spanner values are retained as listed and should be checked against the approved drawing.
How the Metal Gland Is Assembled
The catalog identifies a compression cap, clamping insert, rubber sealing insert, gland body, sealing washer and locknut. Confirm which parts are included with the selected model and whether the mounting entry uses a threaded hole or a through-hole with a locknut.
Why Choose TONFUL Cable Glands
Plastic & Metal Options
Compare lightweight PP plastic constructions with nickel-plated brass options, then confirm the material and seal for your operating environment.
Multiple Thread Families
Select the exact PG, metric, G or NPT entry specified for the enclosure. Thread names and sizes must match the approved installation drawing.
Cable Entry & Retention
The compression and clamping components secure the cable entry when correctly selected and installed. Confirm the cable range, retention requirements and tightening instructions.
Dimensions for Fit Review
Use the catalog tables to compare bore or cable range, thread dimensions, overall height and spanner access. Check the final drawing for the chosen model.
Sealing Review for the Assembly
Review the cable seal and enclosure interface together. Specify any required ingress-protection tests and the installation conditions under which they apply.
OEM Selection & Packing Support
Provide the model, cable size, thread and accessory requirements to discuss samples, identification, pack quantities and repeat supply.
Select a Cable Gland in Six Steps
Step 1: Measure the Cable
Provide the actual cable outside diameter, jacket material and roundness. Select the seal and clamping arrangement specified for that cable.
Step 2: Confirm the Entry Thread
State the exact thread family, nominal size and pitch. Check whether the enclosure uses a threaded entry or a through-hole and locknut.
Step 3: Review Mounting Dimensions
Compare thread length with the enclosure wall, and check overall height, spanner clearance and the required sealing washer or gasket.
Step 4: Choose Material & Sealing
Review plastic or metal construction, seal material, temperature, UV, moisture and chemical exposure. Obtain the performance evidence required for the application.
Step 5: Evaluate the Complete Assembly
Use an approved sample on the actual cable and enclosure. Follow the tightening instructions and review retention and ingress-protection checks under agreed conditions.
Step 6: Agree the Order Details
Confirm the exact model, drawing revision, included accessories, quantity, labels, packing and documentation before volume supply.
Request Samples for Cable Entry Evaluation
Share the cable size, entry thread and enclosure details to discuss model selection, sample availability and evaluation requirements.
Cable Gland Workshop & Packaging
Component Assembly & Dimensional Inspection
Discuss body and thread dimensions, compression-cap fit, clamping inserts, seals and locknuts against the approved drawing. Define material identification, thread checks, assembly inspection and any agreed retention or sealing tests for the selected model. Confirm sampling and inspection records in the order specification.
Sorted Bags & Protective Export Cartons
Specify the quantity per bag and whether compression caps, seals, washers and locknuts are supplied assembled or separately. Labels can identify material, thread family, model and batch details. Agree inner protection and outer cartons to help distinguish similar-looking sizes and protect threads during transport.
Workshop and packaging images are generated illustrations, not photographs of the TONFUL factory or an actual shipment.
More Than Just a Cable Gland Supplier
Cable & Thread Selection Support
Send the cable outside diameter and exact entry thread to focus the model and sealing review.
Drawing & Sample Comparison
Compare mounting length, bore or cable range, spanner access and accessories with your approved sample or drawing.
Assembly & Documentation Review
Define material, sealing, retention and compliance evidence required for the selected model and installed assembly.
OEM Packing & Delivery Planning
Agree model labels, accessory inclusion, pack quantities, destination and shipping terms in the quotation.
Cable Glands: Frequently Asked Questions
Q1: What does a cable gland do?
It provides a controlled cable entry into an enclosure and can clamp and seal around the cable jacket when correctly specified and installed. Review both the cable seal and the gland-to-enclosure interface.
Q2: Which materials are shown in this range?
The supplied catalog describes PP plastic cable glands and nickel-plated brass cable glands. Confirm the precise body, clamping insert and seal materials for the selected model.
Q3: Which thread families are available?
Plastic models are listed in PG and metric forms. Metal models are listed in PG, metric, G and NPT forms. Match the exact designation and pitch to the enclosure drawing.
Q4: Is the plastic D1 value a clamping range?
No. The plastic tables label D1 as the cable entry bore diameter. They do not give a minimum-to-maximum clamping range. Ask for the selected model’s verified cable fit and sealing range.
Q5: Why are there two M25 x 1.5 metal entries?
The catalog lists separate 12-16mm and 13-18mm cable ranges with different height and spanner values. Specify the complete cable-range and dimensional variant when requesting a quote.
Q6: Are all models IP68 certified?
The catalog carries an IP68 mark, but it does not supply model-specific reports or test depth and duration. Request the evidence and installation conditions for the exact gland, cable and enclosure assembly.
Q7: Are metal glands automatically suitable for armoured cable, EMC or hazardous areas?
No such suitability is established by this catalog. Request a specifically designed and documented model where armoured-cable termination, EMC bonding or hazardous-area approval is required.
Q8: What should I send for a quotation?
Provide material, thread family and size, cable outside diameter and jacket, enclosure wall details, environment, required approvals, accessories, quantity and packing preferences. Include a drawing or sample where possible.
