Adjustable Sealing for Reliable Pipe Penetrations
Hauff-Technik HSD mechanical seals are designed for sealing new or already installed pipes in core drill holes and wall sleeves. The HSD SSG version uses continuously variable super segmented ring technology, allowing the pipe press seal to be adjusted directly on site to suit the carrier-pipe diameter.
An integrated inspection window provides visual and physical installation control, while the segmented construction includes diameter markings for easier adjustment. This makes the system suitable as a pipe penetration seal where reliable fit and controlled compression are required around pipe entries.
The seal is FHRK-certified, uses a stable U-profile press-segment design, and is suitable for waterproof-concrete stress classes 1 and 2. Depending on the configuration, stainless-steel V2A or V4A hardware and EPDM or NBR rubber can be used, supporting a durable pipe wall penetration seal for varied project conditions.
Dutco supplies pipe press seals for reliable sealing of pipe penetrations and entries in building and infrastructure applications. These systems provide a gastight, watertight and radon-proof penetration seal for projects requiring dependable pipe-entry protection.

Standout Features & Benefits
On-Site Diameter Adjustment
- Super segmented ring technology enables adjustment to the actual carrier-pipe diameter.
- Reduces dependence on one exact pre-cut pipe opening.
- Diameter markings make the installation process easier to control.
- Provides a flexible pipe press seal for different pipe sizes.
Reliable Watertight Protection
- Forms a gastight and watertight barrier around the penetration.
- Suitable for waterproof-concrete stress classes 1 and 2.
- Helps create a durable watertight pipe seal where the integrity of the wall opening must be maintained.
Retrofit-Friendly Installation
- HSD SSG is supplied split as standard.
- Can therefore be fitted around pipes that are already installed.
- Avoids the need to slide the seal over the pipe end.
- Makes it practical for refurbishment and retrofit pipe entry seal requirements.
Durable Material Options
- Stainless-steel V2A (AISI 304L) or V4A (AISI 316L) press plates, screws and nuts are available.
- EPDM and NBR rubber options support different service conditions.
- Alternative HSD configurations provide additional material combinations for specialised applications.
Certified & Controlled Installation
- FHRK-certified construction.
- Integrated inspection window provides visible and physical installation control.
