Numbering System

Understanding the Elasto Proxy Numbering System

Elasto Proxy uses a standard numbering system to identify the products you can buy from our catalog. Please use this numbering system when ordering, and to indicate a seal’s specifications. As the rest of this page explains, these numbers represent specifications such as diameter, material, and hardness. Elasto Proxy assigns products to these categories.

Since different kinds of products have different specifications, our numbering system varies by category. Please refer to the examples below for details. In each example, note that the links jump to pages that let you see all of your choices for that specification (e.g., diameter, material, hardness).  

Cord Stock

Cord stock is identified by category code, diameter, material, and hardness. There are four different types of cord stock. Each has its own category code. Choose from O-ring cord (ORC), quad O-ring cord (ORCQ), sponge O-ring cord (ORCSP), and square O-ring cord (ORCSQ).

Example: ORC-118-S60

ORC Category Code
118 Diameter
S Material
160 Hardness

Floor Matting

Floor matting is identified by category code, thickness, direct width, custom indicator code (optional), and material. There is only one category code (FM) for floor mats. When used, there is only one custom indicator code (Z). Floor matting is available in many different thicknesses, direct widths, and materials.  

Example: FM-375-43-ZM

FM Category Code
375 Thickness
43 Direct Width
Z Special Code
M Material

Heater Hose

Heater hose is identified by category code, diameter, and material. Although there is just one category code (HH), heater hose is available in a variety of diameters and materials.

Example: HH-375-E

HH Category Code
375 Diameter
E Material

Latches

Latches are identified by category code, three-digit part number code, material, and hardness. There is only one category code (RHT) for latches, but products are available in different materials and hardnesses.

Example: RHT-002-SS

RHT Category Code
002 Part #
S Material
S Hardness

Molded Bumpers

Molded bumpers are identified by category code, three-digit part number code, material, and hardness. There is just one category code (MB) for molded bumpers, but products come in different materials and hardnesses.

Example: MB-002-C80

MB Category Code
002 Part #
C Material
80 Hardness

Profiles

Sponge and solid profiles are identified by category, shape, part number, material, hardness, and adhesive. There are separate category codes for sponge (EC) and solid (ES). Note also that there is a relationship between profile shape and hardness. 

This example is for a sponge (EC) profile.

Example: EC04-030-EMT*

EC-ES Category Code
04 Shape
030 Part #
E Material
M Hardness
T* Adhesive

This example is for a solid (ES) profile.

Example: ES12-001-S50W

EC-ES Category Code
12 Shape
001 Part #
S Material
50 Hardness
W Color

Sheet Stock

Sheet stock is identified by category code, thickness, direct width, material, hardness, and adhesive. There is just one category code (SH) for sheet stock, but many choices for the other specifications. Thickness is measured in fractions of inches while direct width is a whole-inch measurement.

Example: SH-187-42-NMT

SH Category Code
187 Thickness
42 Direct Width
N Material
M Hardness
T Adhesive

Tubing

Tubing is identified by category code, inside diameter, outside diameter, material, and hardness. There is just one category code (ES30) but many choices for the other specifications.

Example: ES30-5866-S60

ES30 Category Code
58 Inside Diameter
66 Outside Diameter
S Material
60 Hardness

Weather Stripping

Weather stripping is identified by category code, thickness, width, material, hardness, and adhesive. There is only one category code (ST), but many choices for the other specifications.

Example: ST-125-21-NMT

ST Category Code
125 Thickness
21 Width
N Material
M Hardness
T Adhesive

Custom Indicator Code

Products that have custom indicator codes (Z) contain miscellaneous compounds that impart different characteristics than the rubber materials used in standard products. Custom indicator codes are always designated by the letter “Z”. Floor matting, sheet stock, and weather stripping are the categories that contain the most products with Z codes. However, any product can have a custom indicator code if it’s made from a non-standard compound and has miscellaneous characteristics.   

Three-Digit Part Number Code

Three-digit part number codes are assigned at random and do not represent physical attributes. Latches, molded bumpers, and sponge and solid profiles contain these three-digit part number codes. Products in other categories do not.
