What launched, and when
HERZ Armaturen Ges.m.b.H. has its first set of Environmental Product Declarations on the record, issued in October 2025. The initial wave contains two product‑specific EPDs that read as representative items from the company’s fittings portfolio. Validity windows point to current coverage through 2030, which is plenty of runway for today’s specs.
What the EPDs cover
Both declarations focus on press fittings designed for in‑building plumbing and heating systems. Materials noted include brass for heating use and PPSU for potable water components, with stainless steel sleeves and EPDM sealing elements typical for this class of coupling. In plain terms, these are the small but mighty connectors that make distribution lines leak‑tight, serviceable, and fast to install. That is exactly where many submittal packages ask for product‑specific EPDs now.
Program operator at a glance
The new EPDs are published with EPD Hub, a digital‑first program operator aligned to EN 15804 and ISO 14025. If readers want a quick primer on how that operator works in practice, see our overview of EPD Hub for governance, rule‑set notes, and publishing flow.

Why this matters for HERZ’s core market
HERZ is best known for HVAC and plumbing hardware for multi‑family, commercial, education, and healthcare buildings, from radiator valves and actuators to balancing valves and press systems. EPDs for fittings land right where specifications harden, since MEP teams often apply conservative factors when a product‑specific EPD is missing. With these declarations, HERZ products slot into submittals without that drag, which can shorten decision cycles and keep projects from defaulting to a competitor simply because paperwork is cleaner.
Competitive snapshot
Viega shows broad EPD coverage across press connectors and piping systems with European operator listings that specifiers recognize, so HERZ is stepping into an active lane rather than a blank field. Uponor also lists multiple current EPDs across piping and radiant system components, which means buyers already compare within that family during substitutions. IMI Hydronic Engineering has current declarations for balancing valves and couplings that touch adjacent scopes. Net‑net, HERZ is catching up to established names in fittings and hydronics, and that move keeps them in the room when EPDs are a gate rather than a nice‑to‑have.
Will teams find these EPDs easily
As of June 22, 2026, we could not locate these specific EPD PDFs on HERZ’s corporate or regional websites. Visibility matters because many project teams start at the manufacturer’s downloads page before they hunt operator libraries. We recommend adding a clear Sustainability or EPD page with direct PDFs per product family so reps, distributors, and specifiers can grab them in seconds. That is free commercial lift hiding in plain sight.
A note on timing and discoverability
Operator issuance and public directory listing are not always simultaneous. We routinely see a lag of weeks to months between a publication date and full visibility in the global tools design teams use. That delay is avoidable. If future EPDs need to show up in those directories within a day or two, reach out and we will share the playbook that closes that gap.
What good next steps look like
There are two quick wins. First, extend coverage from fittings into the adjacent valve and control families that frequently ride the same bill of materials. Second, publish a short installer‑facing summary that explains what the EPD covers and how to reference it in submittals. Keep the PDFs one click from the product page. Sounds simple, but it is definitley the difference between being considered and being swapped out.
The takeaway
HERZ has moved its fittings from brochure to proof. The first EPDs give specifiers the confidence to keep HERZ on schedules when carbon tracking tightens. Competitors in this space already play the EPD game, so this debut is about staying in every conversation and growing share where paperwork decides the final shortlist.
