Seal and retain a cable at an enclosure entry using a gland matched to cable dimensions, thread geometry and environmental exposure. The buying process should establish cable outside diameter, entry thread, sealing arrangement, and mechanical retention. Use the comparison checkpoints to prepare a consistent quotation request, define installation and acceptance responsibilities, and identify missing accessories or evidence. OEM/ODM is a project-specific feasibility question; request written confirmation of any proposed change and the supporting documentation.

Seal and retain a cable at an enclosure entry using a gland matched to cable dimensions, thread geometry and environmental exposure.
Measure the cable and identify the entry
A cable gland retains and seals a cable where it enters an enclosure. Begin with the measured outside diameter, cable shape and jacket material, then identify the entry thread. Metric, PG and NPT threads are different connection systems; similar-looking dimensions do not make them interchangeable. Record the enclosure wall thickness and whether the entry is threaded or uses a clearance hole and locknut.
Choose the sealing range for the actual jacket
A gland has a specified cable-clamping range, not unlimited adjustment. The cable must sit within the range of the selected insert, with a jacket compatible with the seal and expected conditions. Unusual cable shapes or multiple cables may require a purpose-designed insert. Do not assume an ordinary round-cable gland can seal flat cable, a bundle or a damaged jacket. Request the relevant dimensions for the exact part.
Treat ingress protection as an installed assembly
A gland rating does not independently guarantee the rating of an enclosure assembled with it. The entry geometry, seal arrangement, washers, O-rings and installation procedure influence performance. HUMMEL’s HSK-K information, for example, distinguishes conditions involving an additional O-ring. Specify the complete installation and ask what supporting evidence applies. Avoid carrying a catalogue rating over to a different wall, cable or accessory arrangement without checking the conditions.
| Buying checkpoint | Project information |
|---|---|
| Cable outside diameter | Select the seal range for measured cable dimensions and jacket material. |
| Entry thread | Identify metric, PG or NPT and required engagement length. |
| Sealing arrangement | Check washers, O-rings, enclosure wall and installation method. |
| Mechanical retention | Assess strain relief, movement, bend control and installation torque. |
| Material and exposure | Match polyamide or metal to chemicals, UV and temperature. |
| EMC or hazardous area | Request a specifically suitable design and supporting evidence where required. |
Check retention, movement and materials
Strain relief and sealing are related but different jobs. Describe cable movement, vibration and any pull or bend exposure at the entry. Choose body and seal materials for temperature, chemicals, sunlight and cleaning conditions. Plastic and metal glands have different application considerations; material alone does not settle suitability. The specified tightening method also matters, so provide installation access and request the applicable torque or assembly instructions rather than improvising with tools.
Separate EMC and special-area requirements
A conventional gland should not be assumed to provide a designed shield connection. EMC applications need a suitable construction and a documented method of contacting the cable screen. Hazardous-area installations involve additional equipment selection and documentation requirements that cannot be inferred from an ordinary enclosure rating. State these needs at the inquiry stage. Ask for evidence tied to the exact gland variant and installation conditions, rather than a general certificate logo.
Order the gland and its accessories together
Create a part schedule covering thread, sealing range, material, cable type, quantity and accessories. Include locknuts, thread seals, blanking elements or reduction pieces where the design requires them, and check whether they change the assembly conditions. Retain part numbers for maintenance. A cheaper substitute may use a different seal range or thread length, creating an installation problem even when its nominal trade size appears comparable.
Define OEM/ODM by an installation drawing
Potential changes include color, labeling, thread length, seal material or an application-specific insert. Each can affect dimensions, performance or documented approvals. Supply a cable cross-section and enclosure-entry drawing and identify the environment. The feasibility response should state tooling, sample testing and evidence required for the modified part. A HUMMEL reference image describes a gland design; it does not establish a private-label supply arrangement.
What should your cable gland RFQ include?
- Cable outside diameter: Select the seal range for measured cable dimensions and jacket material.
- Entry thread: Identify metric, PG or NPT and required engagement length.
- Sealing arrangement: Check washers, O-rings, enclosure wall and installation method.
- Mechanical retention: Assess strain relief, movement, bend control and installation torque.
- Material and exposure: Match polyamide or metal to chemicals, UV and temperature.
- EMC or hazardous area: Request a specifically suitable design and supporting evidence where required.
- Project location, destination requirements and intended operating environment
- Required drawings, connection information and site responsibility boundaries
- Representative acceptance case, documentation, training and spare-parts scope
- OEM/ODM: proposed branding, interface or design changes; engineering feasibility and evidence required
Need OEM / ODM customization?
Submit branding, packaging, configuration or engineering requirements for this equipment. Include the target market, initial and annual quantities, required changes and acceptance criteria.
Customization feasibility, permitted branding, development responsibilities, minimum quantity, cost and lead time are reviewed for the proposed supplier and configuration before a quotation is confirmed.
Frequently asked questions
Can a PG gland replace a metric cable gland?
PG and metric threads differ and should not be treated as interchangeable. Identify the enclosure entry precisely, including thread specification and engagement requirements. If an adapter is proposed, assess its dimensions and sealing arrangement as part of the complete enclosure assembly.
Which cable diameter should be used for gland selection?
Use the actual outside diameter of the cable jacket where the gland seals, including relevant manufacturing variation. Choose the exact part with an appropriate specified clamping range. The conductor size or a nominal cable designation does not establish the outside diameter.
Does an IP-rated gland guarantee the enclosure rating?
No. Performance depends on the installed assembly, including cable fit, entry, seals, washers and installation method. Check the manufacturer’s conditions and the complete enclosure design. Additional accessories or an unsuitable jacket can change the result even when the gland itself has a stated rating.
Is every metal cable gland an EMC gland?
No. EMC performance requires a suitable shield-contact design and installation arrangement. A metal body alone does not define how the cable screen connects. Describe the screening requirement and request the exact variant, assembly instructions and supporting technical information for the proposed cable.
What accessories should be specified with a gland?
List any locknut, thread seal, O-ring, reducer or blanking component required by the installation drawing. Confirm material and dimensional compatibility. Accessories are part of the sealing and mechanical arrangement and should not be left to an unspecified substitute at installation.
Can a special gland insert or thread be customized?
Submit cable geometry, entry dimensions, environment and required retention or sealing performance. A manufacturer may assess special inserts, materials or thread lengths, but changes can require tooling and tests. Confirm the evidence applicable to the modified assembly before approving an OEM/ODM order.
