What SEALABLE Solutions does

SEALABLE Solutions GmbH is a German manufacturer of rubber-based sealing and insulation solutions, organized into three application areas: Tunnelling, Track Superstructure, and Industrial Solutions. The company sells primarily to enterprise and government customers in the railway, tram, and tunnel construction sectors, with documented projects in over 790 tunnel references across Europe, Asia, the Americas, and Oceania. Its portfolio includes the RCS Rail Comfort System (elastic rail encapsulation for vibration isolation and stray current insulation), the VeloGleis bicycle-safe track system, Blackswell hydrophilic swelling rubber for tunnel segments, and various anchored, bonded, coex, and fiber-anchored segment seals. Technology differentiation rests on proprietary elastomer formulations (including bio-based rubber using sugarcane-derived ethylene and a wood-based functional filler used in RCS Greenline), 43 patents, REACH compliance, CE marking on segment gaskets, and an in-house Technikum testing laboratory with STUVA certification capabilities.

The company traces its origins to fire hose production more than 200 years ago and its modern rubber-sealing expertise to over 50 years of ownership through PHOENIX AG, ContiTech AG, PHOENIX Dichtungstechnik GmbH, and DÄTWYLER Sealing Technologies Deutschland GmbH. Following a management buy-out in May 2020 led by Managing Directors Dr. Matthias Orth and Matthias Klug, SEALABLE operates as an independent Thuringian firm headquartered in Waltershausen. Revenue is generated through project-based custom manufacturing with quote-based B2B pricing, sold via direct enterprise field sales organized by region and application area (Tunnelling, Track Superstructure, Industrial Solutions), supplemented by an extensive agent and distributor network covering more than 40 countries. In January 2026, the company joined the Elastofirm B.V. corporate group while continuing to operate as SEALABLE Solutions GmbH.

Direct peers

• Datwyler: Swiss industrial supplier that was SEALABLE's parent company (as Dätwyler Sealing Technologies) prior to the 2020 management buy-out. Datwyler continues to produce elastomer sealing solutions for automotive, healthcare and industrial customers, making it the most directly comparable peer.
• Greene Tweed: US-headquartered manufacturer of high-performance seals, gaskets and engineered composite components serving industrial, semiconductor, oil & gas and aerospace markets. Comparable as a specialty elastomer/sealing peer focused on engineered custom solutions.

Broad incumbents

• ContiTech (Continental): Continental's ContiTech division is one of the world's largest rubber and elastomer technology groups, offering industrial hoses, vibration control and sealing profiles. It was a historical owner of the Waltershausen site (ContiTech AG) and remains a broad incumbent overlapping with SEALABLE's rubber profile and vibration isolation portfolio.
• Trelleborg: Global engineered polymer and sealing solutions group with significant business in infrastructure sealing, antivibration and railway applications. Directly competes with SEALABLE on tunnel sealing profiles and rail vibration isolation, but at much greater scale across many other polymer end markets.
• Freudenberg Sealing Technologies: Part of the Freudenberg Group, one of the world's largest manufacturers of seals and gaskets for automotive, industrial and process industries. Competes with SEALABLE on custom elastomer sealing solutions and offers overlapping capabilities in railway and industrial vibration/sealing.
• Hutchinson (TotalEnergies): TotalEnergies-owned specialist in vibration management, sealing systems and fluid transfer for automotive, aerospace, rail and industry. Directly comparable on rail vehicle glazing/damping and industrial sealing solutions segments where SEALABLE operates.
• Parker Hannifin: Global motion and control technologies leader with a substantial sealing solutions portfolio (O-rings, gaskets, custom elastomer seals). Overlaps with SEALABLE on industrial pipe seals, window/facade seals and engineered rubber profiles.
• Phoenix AG: Historical owner of the Waltershausen business (as PHOENIX AG) before ContiTech and Datwyler. Phoenix AG is a German rubber products and hose manufacturer; relevant as both a historical predecessor owner and a current broad rubber products peer.

Others

• Elastofirm B.V. Dutch corporate group that acquired SEALABLE in January 2026. Elastofirm operates a portfolio of elastomer companies and is comparable as the parent platform; also serves as an adjacent group with potential product/customer overlap.

Regional players

• Hennlich: Central European industrial distributor and manufacturer of technical rubber products, profiles and sealing solutions. Comparable as a regional rubber profile peer serving similar industrial and rail customers across DACH and CEE markets.
