standard lip standard head |
EH1A EH2A |
3,000 psig | The EH1A and EH2A series are best suited for very slow or static applications where tight sealing in light fluids and gases is important. Also a very good choice for low pressure applications. |
I.D. Scraper Standard Heel |
EH1B EH2B |
3,000 psig | Used in reciprocating rod applications with viscous fluids. The scraper lip can also be used to "snap" the seal into stepped glands. |
O.D. Scraper Standard Heel |
EH1C EH2C |
3,000 psig | Used in reciprocating piston applications with viscous fluids. The scraper lip can also be used to "snap" the seal into stepped glands. |
Double Scraper Standard Heel |
EH1D EH2D |
3,000 psig | Good for the combination of a stepped gland and reciprocating motion. |
Standard Lip Extended Heel |
EH3A EH4A |
10,000 psig | Same as EH1A and EH2A series but with greater pressure capabilities. |
I.D. Scraper Extended Heel |
EH3B EH4B |
10,000 psig | Same as EH1B and EH2B series but with greater pressure capabilities. |
O.D. Scraper Extended Heel |
EH3C EH4C |
10,000 psig | Same as EH1C and EH2C series but with greater pressure capabilities. |
Double Scraper Extended Heel |
EH3D EH4D |
10,000 psig | Same as EH1D and EH2D series but with greater pressure capabilities. |
Internal Face Seal |
EH5A | 3,000 psig | An excellent alternative to elastomers in applications with difficult combinations of temperature and pressure and little to no motion. The EH5A series seals pressure from an internal source. |
External Face Seal |
EH6A | 3,000 psig | An excellent alternative to elastomers in applications with difficult combinations of temperature and pressure and little to no motion. The EH6A series seals pressure from an external source. |
Material Code | Description | Typical Applications | Temp Range | COF (µ) |
---|---|---|---|---|
E400 | Virgin PTFE Color: White |
An FDA compliant, light duty material. Good in light gases and cryogenic applications. | -400 to +450 | .05 / .08 |
E471 | Graphite Filled PTFE Color: Black |
The graphite filler in this blend acts as a dry lubricant making it a good choice in dry running services. | -320 to +475 | .06 / .10 |
E431 | Glass/ Moly Filled PTFE Color: Dark Gray |
A highly wear resistant blen good for high speed applications on hardened shafts. | -250 to +550 | .06 / .10 |
E462 | Carbon/ Graphite Filled PTFE Color: Dark Gray |
A good material choice for combinations of speed and temperature. | -320 to +475 | .08 / .12 |
E491 | Ekonol Filled PTFE Color: Beige |
This blend uses a non-abrasisve polymer filler. Best in dynamic applications running against soft metals. | -200 to +550 | .08 / .12 |
E282Z | Carbon/ Graphite/ PPS Filled PTFE Color: Black |
Heavy duty material reserved for the most difficult combinations of temperature, speed and pressure. | -200 to +550 | .08 / .12 |
E220 | Thermoplastic Elastomer Color: Black |
When corrosion resistance and temperature extremes are not the primary concerns TPE is a good choice for tight sealing. | -80 to +275 | .30 / .60 |
E010 | UHMW-PE Color: Translucent White |
An FDA compliant material with very good wear resistance. | -320 to +200 | .15 / .25 |
E020 | Acetal Color: Brown |
As a backup ring this material has good extrusion resistance with low water absorption. | -70 to +250 | .30 / .40 |
E125 | PEEK Color: Tan |
A high-modulus, engineered plastic with excellent thermal and mechanical properties. | -100 to +550 | .35 / .45 |
