Engineering Resources & Guides
Datasheets, industry briefs, calculators, compatibility charts and how‑to‑spec guides for gasket, tape and thermal material selection — free to use, with no forms and no gates.
Every reference is written to be kept: materials starting points, compression design windows, example drawing notes and the RFQ checklist.
All products are custom manufactured to order. Minimum production run quantities apply.
Pick the resource type you need.
Eight collections, one goal: get you from “what material?” to a quotable drawing faster.

Read the guide →Don’t see the document you need?
Datasheets, compliance statements and test reports are added as customers ask for them. Tell us the material or the requirement, and an engineer sends it to your inbox — usually the same business day.
Before you dig in.
Are any of these resources gated behind a form?
No. Every datasheet, industry brief, calculator and chart on this site is free to use and download with no form, no login and no follow‑up sequence. If a document is worth keeping, it should be easy to keep.
Can I order a stock part straight from a datasheet?
H‑O is a custom converter: all products are custom manufactured to order, and minimum production run quantities apply. Datasheets tell you what the material can do — your drawing tells us what to make from it. Send both with your RFQ and we’ll confirm format, tolerance and minimums at quote.
Is H‑O ISO certified?
Yes — H‑O Products Corp. is ISO 9001:2015 certified by Amtivo (USA) Inc., an ANAB‑accredited registrar, covering the development and manufacturing of standard and custom tapes, pads and gaskets. First Article Inspection aligned with AS9102, PPAP packages and full lot, batch and material traceability are available on contract. Download the current certificate (PDF).
How do I go from a resource to a quote?
Use the RFQ checklist in any industry brief: part drawing or geometry, material or performance requirement, quantities and any compliance callouts. Send it through the contact form or call the desk at (860) 469‑1144 — an engineer, not a ticket queue, picks it up.
Documents in this library are provided for engineering reference. Property values are typical unless expressly stated as specifications; confirm specification‑critical values with H‑O engineering at quote. Product names and trademarks belong to their respective manufacturers.
