SealMaster-HV is a dual-orientation EPDM compression seal that performs in both horizontal and vertical expansion joints. Supplied in 10 standard sizes plus custom profiles, the solid EPDM rubber is compressed into the joint cavity and is widely specified for firewalls, floors, concrete slabs, steelwork, cavity joints and ventilation ducting where anti-vibration sealing is required.
SealMaster-HV seals joint gaps of up to 120 mm and is engineered to remain unaffected by water, oil and many chemicals. Its weather-resistant EPDM compound keeps its elasticity and sealing pressure under structural movement and vibration, making it a flexible single solution for a broad range of industrial and commercial joints.
Key Benefits
- One seal handles both horizontal and vertical joints, simplifying specification

Technical Specifications
| Type | EPDM seal (horizontal & vertical) |
|---|---|
| Max gap | 120 mm |
| Sizes | 10 standard + custom |
| Resistance | Water, oil, chemicals |
Installation Guide
- Clean both joint faces, removing oil, dust and loose debris
- Measure the gap and select the standard or custom SealMaster-HV size up to 120 mm
- Prepare and prime the joint arrises as recommended
- Apply adhesive lubricant to the seal and joint contact surfaces
- Compress the EPDM profile and insert it into the joint, horizontal or vertical
- Ensure even compression along the full length with no twists or gaps
- Remove surplus adhesive and inspect the seal for continuity
Maintenance & Care
SealMaster-HV is low maintenance even in demanding industrial settings. Keep joints clear of oil pools, grit and debris and wipe down the seal face during routine plant cleaning. Inspect joints periodically, with extra attention to areas exposed to chemicals, vibration or heavy traffic.
Check that the EPDM remains firmly compressed, has not been pushed out by vibration, and that the sealing face is intact and free of cuts. Because the compound resists oil and chemicals it does not degrade in typical industrial exposure; any damaged section can be replaced individually. Dhawan Associates can supply matching standard or custom lengths.
FAQs
SealMaster-HV — Frequently Asked Questions
What is SealMaster-HV?
SealMaster-HV is a Dseal EPDM compression seal that works in both horizontal and vertical expansion joints. The flexible rubber profile is compressed into the joint to seal it while accommodating movement and vibration.
What material is SealMaster-HV made from?
It is made from solid EPDM rubber. This elastomer gives it resistance to water, oil, many chemicals and weathering, which is why it suits industrial joints. Dseal manufactures it in India.
What is the maximum joint gap for SealMaster-HV?
SealMaster-HV seals joint gaps of up to 120 mm. The right profile is chosen from the 10 standard sizes, or a custom size, to match your specific gap.
Is SealMaster-HV resistant to oil and chemicals?
Yes. SealMaster-HV is unaffected by water, oil and a wide range of chemicals, making it well suited to industrial floors, plant rooms and process areas.
Can SealMaster-HV be used for vertical joints?
Yes. Unlike a horizontal-only seal, SealMaster-HV is rated for both horizontal and vertical joints, so one product covers slabs, walls and cavity joints.
Is SealMaster-HV weather resistant?
Yes. The EPDM compound resists weathering and retains its elasticity outdoors, so the seal performs reliably in exposed as well as internal joints.
How does SealMaster-HV handle vibration?
It offers anti-vibration sealing, which is why it is specified around ventilation ducting and steelwork connections where vibration would loosen a rigid seal.
How is SealMaster-HV installed?
The joint is cleaned, lubricant adhesive is applied, and the correctly sized EPDM profile is compressed and inserted into the horizontal or vertical joint to a uniform compression.
What standards back SealMaster-HV?
It is made by Dhawan Associates, certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 covering quality, environment and occupational safety.
How is SealMaster-HV different from SealMaster-H?
SealMaster-H is for horizontal floor and wall joints only, while SealMaster-HV adds vertical capability, gaps up to 120 mm and broader oil and chemical resistance for industrial use.
Are custom sizes of SealMaster-HV available?
Yes. Beyond the 10 standard sizes, Dseal makes custom profiles to suit unusual joint widths. Contact Dhawan Associates with your dimensions for a tailored size.
How many standard sizes does SealMaster-HV come in?
SealMaster-HV is offered in 10 standard sizes, with custom profiles available on request to match the exact joint gap on your project.
Where is SealMaster-HV used in buildings?
It suits firewalls, floors, concrete slabs, steelwork, cavity joints and ventilation ducting, covering a broad range of industrial and commercial movement joints.
Who manufactures SealMaster-HV?
SealMaster-HV is manufactured in India by Dhawan Associates under the Dseal brand, a leading name in expansion joint systems and covers.
Where can I buy SealMaster-HV in India?
Buy SealMaster-HV directly from Dseal (Dhawan Associates). Call +91 93109 97953 for sizing advice, standard or custom options and ordering.
Does SealMaster-HV need maintenance?
Very little. Keep the joint clean and inspect it periodically to confirm the seal stays compressed and intact. Damaged lengths can be replaced individually.
Is SealMaster-HV suitable for firewalls?
Yes. SealMaster-HV is commonly specified for firewall expansion and movement joints as part of its broad industrial and commercial application range.
