Independent panel-hardware sourcing

rubber grommets

Rubber Grommets Sourcing is an independent sourcing partner for US buyers. Share inner and outer diameter or a named size reference, compound, Shore A hardness the factory must confirm, quantity and destination so wholesale quotes can sit on the same line. We do not mold parts, hold warehouse stock, or sell under a brand appointment.

Files belong to a named rubber grommets line

REACH, RoHS, FDA 21 CFR, ISO 9001, IATF 16949 and UL 94 marks are supplier or grade evidence. Rubber Grommets Sourcing does not publish a house badge wall. Ask the factory for the current document that names the quoted compound, lot and configuration.

REACH

Ask for the SVHC statement that names the quoted rubber grommets compound, not a trading-company letter.

RoHS

Use when the panel assembly has to travel into an electrical bill of materials.

FDA 21 CFR

Only when the buyer named food-contact service. The file must cite grade and lot.

ISO 9001

Plant quality-system evidence. It does not replace a dimensional report on the grommet.

IATF 16949

Ask when the line is automotive rubber grommets, then still confirm ASTM D2000 callouts.

UL 94

Flame rating is a material claim. Reprint it only from the factory page that covers that compound.

What a factory needs before it can answer rubber grommets

The buyer still chooses panel hole or groove size, cable outer diameter if the part is for wires, compound family and the medium. The factory only confirms what it can mold or punch on that request.

TDS / size library

Request a current dimensional page. Inner diameter, outer diameter and panel thickness belong together. A photo of a black ring is not a size.

Axes the buyer writes
Axis	How to write it
ID / OD	inch or mm, or a named standard size
Panel	hole diameter and sheet thickness

Material selector

NBR, FKM, silicone and EPDM are different goods. Shore A is a question the supplier must confirm. Do not mix Shore A with Shore D on the same line.

Compound questions
Ask	Why
Shore A	Elastomer hardness, not a published stock rating
ASTM D2000	Line callout the factory must map to the quote

CAD and groove notes

A drawing-based option is a different request from a catalogue ring. Send the drawing after we reply; this site has no upload field.

Send the groove note

Three checks before rubber grommets leave the desk

Name the form

Separate rubber grommets from a closed rubber grommet plug, a continuous rubber grommet strip, or a neighbouring family. The buyer keeps that naming decision.

Write quantity by configuration

Quantity belongs against each inner/outer pair and compound, plus sample versus production lot, packing and destination US state or postal code.

Compare the same scope

This desk sends one list to more than one factory. A plant certificate is not a lot test. A unit price without Incoterms is a different deal.

Procurement situations, not customer testimonials

These cards are checklists for typical US buyer situations. They are not named reviews, savings claims, or completed orders.

“A cabinet shop replacing rubber grommets on a 0.06 inch steel panel still has to name panel-hole diameter, cable outer diameter and Shore A. A photo of a black ring is not a specification.”

Scenario A
Materials manager · Control cabinets · US Midwest

“A harness buyer mixes nitrile and EPDM on one purchase order only when each inner/outer pair and compound is a separate quantity row.”

Scenario B
Commodity buyer · Automotive harness · US South

“An unused hole that started as a rubber grommet plug search still needs closed-end versus open, panel thickness, and the document set that travels with the lot.”

Scenario C
Plant engineer · Appliance chassis · US West

Checks this desk repeats on every rubber grommets brief

ID / OD

Inner and outer diameter or a named size reference stay the buyer’s decision.

Shore A

Hardness is confirmed by the supplier against the named compound, not guessed here.

°F or °C

Service temperature is written with the medium. This desk does not publish a stock range.

No SKU stock

Five reviewed inquiry options. Zero warehouse SKUs claimed by this desk.
