PresSure Products Company: EPDs, gaps, and upside

What PresSure Products Company makes

PresSure Products Company (PPC) is a U.S. manufacturer of process observation and safety hardware. The catalog centers on sight glass windows, fused sight glasses, sanitary fittings, sight flow indicators, liquid level gauges, and process lights. PPC also lists reactors and chambers plus accessories like spray rings, wipers, purge rings, and seals.

Product breadth in plain numbers

From the site menus alone, PPC appears to offer multiple dozen product families with many size and material options. That translates into hundreds of SKUs and build‑to‑order variants across pressure classes, glass types, and hygienic connections. In short, this is not a single‑product shop.

EPD coverage as of December 19, 2025

We did not find published, product‑specific EPDs for PPC on their website or across the major operator registries. If one exists, it was not visible through normal buyer discovery paths. That discoverability gap matters once a project team filters for products with verified declarations.

Where EPDs matter for PPC’s portfolio

Sight windows and level gauges are permanently installed building products in labs, food, life‑science, and heavy industrial facilities. Owners increasingly favor products with EPDs for procurement consistency and portfolio reporting. Lighting is an adjacent proof point. One leading brand has released 2,000 EPDs covering about 70,000 product variations, signaling how quickly transparency is spreading in spec‑driven categories (Signify, 2024) (press release).

A likely high‑runner without an EPD

PPC’s Model B and Model L sight glass windows, plus the PPC‑HKB explosion‑proof process light, read like core volume items. Similar luminaires from global lighting suppliers now ship with EPD coverage, which can help them win tie‑breaks on sustainability‑weighted projects. That leaves process lights without EPDs vulnerable to being swapped for catalog fixtures that tick the declaration box.

Competitors PPC often meets on projects

• L.J. Star and J.M. Canty for sight glasses and observation lighting
• Jacoby‑Tarbox by Clark‑Reliance and Penberthy for flow indicators and gauges
• Alfa Laval for sanitary sight glasses in food and beverage
• R. STAHL and Dialight in hazardous‑location lighting These are not perfect one‑to‑one matches, yet they are common substitutions during value engineering.

The practical path to first EPDs

Sight windows and flow indicators combine glass, metals, seals, and optional coatings. Upstream data exists for key inputs. For example, a North American flat glass EPD reports about 1,102 kg CO2e per ton for A1‑A3 after a 2024 update, a change that also helps projects meet the U.S. GSA top 20 percent Low Embodied Carbon threshold (Guardian Glass, 2024) (Guardian Glass EPD page). With supplier EPDs in hand, a product‑specific declaration for a representative PPC assembly is achievable.

What to prioritize, in order

Start with one high‑volume, standard‑material sight glass assembly that repeats across many orders. Pick a reference year with clean utility and scrap data, then include common options like gasket type as declared variants. Choose the same PCR framework competitors use so submittals compare cleanly. Next, extend to the sanitary sight window family and a single process light. This staged scope builds momentum quickly without boiling the ocean.

Commercial upside to expect

In LEED‑targeted labs and food plants, product‑specific EPDs remove the penalty that teams often apply when declarations are missing. That means PPC’s products compete on performance and delivery, not just price, and are less likely to be swapped late in design. We beleive even one mid‑sized project win can repay the effort many times over.

Closing thought

PPC already sells into specification‑heavy environments. Turning a few flagship assemblies into verified, findable EPDs would meet buyers where they are and keep the brand in more shortlists when sustainability screens tighten.
