Materials & Resources

Will that elastomer survive your process fluid? Check resistance ratings for over 200 media types against common gasket materials — elastomers, plastics, and metals.

Not sure where to start? This guide walks through service conditions, joint design, and material limits step by step — so you end up with the right seal, not a callback.

The ASME PCC-1 bolt-up sequence, step by step. Covers cross-pattern tightening, torque values, lubricant K-factors, and why the re-torque pass matters more than most people think.

Gasket came out looking wrong? This visual diagnostic covers blowout, thermal degradation, extrusion, and chemical attack — with photos showing what each failure mode actually looks like and what to fix.

EPDM, Nitrile, Neoprene, Silicone — each has trade-offs. This side-by-side comparison helps you pick the right elastomer for your service conditions without over-specifying (or under-specifying).

Use our interactive tolerance checker for DIN 7715-5, ISO 3302-1, and ISO 2768-1. Compare precision classes and access practical guidance to establish realistic manufacturing expectations for die-cut components.

Imperial-to-metric conversion tables for pressure, temperature, torque, length, and force. Printable format — handy for the workshop wall.

Flange dimensions for AS 2129, ASME B16.21, and EN 1514 — all in one place. Look up bolt holes, PCD, and gasket OD/ID without flipping between standards documents.

How much pressure can your flange handle at temperature? Our ASME B16.5 reference tables and interactive derating diagrams show exactly where the limits fall — because a Class 300 flange at 400 °C isn't Class 300 any more.

Shore A hardness, compression set, elongation — and why they matter for bolt load retention. If you've ever wondered whether a Shore A 60 or Shore A 80 gasket is right for your flange, start here.

Getting ID, OD, and PCD right the first time saves everyone a headache. This guide covers how to measure, what to record, and how to write a spec that gets you a correct gasket on the first cut.

What level of inspection does your application actually need? We break down standard dimensional checks, formal material certification, and 100% inspection protocols — including when EN 10204 3.2 certification or third-party witness inspection is worth the added cost.

What do the colour rings on a Spiral Wound Gasket mean? This guide covers ASME B16.20 colour-coding for winding and filler materials, plus when you actually need inner and outer rings.
