Material specifications and data tests sheets for all compounds are available upon request. PPAP documentation is available and pricing will be included with quotations when requested, pricing structure is as follows:
PPAP Level 2 - no charge and includes PSW, dimensional report and material data sheet.
PPAP Level 3 - $250.00 one-time engineering charge.
PPAP Level 4- charge is TBD, depending on customer requirements.
We can engineering drawings based on your sample provided. Engineering fees for reverse engineering a print from a sample are:
RUSH (1-3 days) @ $40.00/hr
Standard (1-2 weeks) @ $30.00/hr
We will require approval of all prints we generate prior to beginning tooling.
In the vast majority of cases, the likeliness of AJRWeb, Inc products containing substances included on the California Proposition 65 list is very low. Our Rotary Shaft Seals have been tested and do NOT contain lead and phthalates. Because not all product and compounds have been been tested for every substance on the CA list, all of our products will be shipped with with a CA Prop 65 warning label, including oil seals. If you require specific information on any AJRWeb compound, please contact us with any questions or concerns.
RoHS and REACH certification, NSF 61 and FDA certification is available for specific compounds upon request.
All product is supplied with a traceable batch and cure.
Understanding ASTM Call-outs for o-rings, related seals and custom molded rubber seals
Specification: ASTM D2000 M3CH 714 A25 B34 EO16 EO36
Measurement Unit: ASTM D2000 M3CH 714 A25 B34 EO16 EO36
M = Metric units will be used for tensile strength, temperature and tear strength.If no M present, Enlish units will be used
Grade number: ASTM D2000 M3CH 714 A25 B34 EO16 EO36
Indicates grade level to which material will be subjected
Type and Class: ASTM D2000 M3CH 714 A25 B34 EO16 EO36
Table below is for most common polymers used. In this example, the material is Nitrile
D 2000 SAE J200
Material Designation (type and Class)
Type of polymer most often used
|AA||Natural Rubber, reclaimed rubber, SBR, butyl, EP polybutadiene, polyisoprene|
|BA||Ethylene propylene, high temperature SBR, butyl compounds|
|BC||Chloroprene polymers (neoprene), cm|
|BE||Chloroprene polymers (neoprene), cm|
|BG||NBR polymers, urethanes|
|BK||NBR (Buna N Nitrile)|
|CE||Chlorosulfinated polyethylene (Hypalon), cm|
|CH||NBR polymers, epichlorohydrin polymer|
|DA||Ethylene propylene polymers|
|DF||Polyacrylic (butyl-acrylate type)|
|DH||Polyacrylic polymers, HNBR|
|FC||Silicone (high strength)|
|HK||Fluorinated elastomers (Viton®,Fluorel, etc.)|
Hardness (durometer): ASTM D2000 M3CH 714 A25 B34 EO16 EO36
Indicates durometer range in Shore A units, (+/- 5 points). In this example, the hardness is 70 +/- 5 durometer.
Tensile strength: ASTM D2000 M3CH 714 A25 B34 EO16 EO36
Indicates maximum tensile strength. In this example tensile strength required would be 14MPa
Additional requirements suffixes: ASTM D2000 M3CH 714 A25 B34 EO16 EO36
Suffixes relate to table below, the letter/number call-outs related to a specific material test and performance requirement per the grade number. Refer to the ASTM D 2000 official standard for expanded call-out requirements. In this example, the suffixes refer to a heat resistance test, a compression set tis, and two fluid resistance tests for oils and lubricants.
|C||Ozone or Weather Resistance|
|EA||Fluid Resistance (Aqueous)|
|EF||Fluid Resistance (Fuels)|
|EO||Fluid Resistance (Oils and Lubricants)|
|F||Low Temperature Resistance|
|Z||Any special test requirement specified in detail|
