TR0 - 3PC NITRILE ROD T-SEAL w/NYLON BACKUPS- INCH

Rod T-seals were originally developed to replace O-rings, and retrofit into standard commercial O-ring grooves. This development ended two serious reliability problems: 1. Extrusion through the clearance gap. 2. Spiral or twisting failure due to instability in the groove. T-seal back-ups are hydraulically or pneumatically driven against the dynamic surface when system pressure forces the elastomer into the space beneath the back-up. This immediate response to pressure makes them very effective wipers, keeping contaminants away from the sealing line. Standard material for our T-seals is 75 durometer nitrile with moly-filled nylon back-up rings. Other materials are available upon request. Temperature: -40°F to +225°F. Pressure: 0 to 5,000 PSI

TDI - Hunger® 2pc Urethane/PTFE Rod Seal - Metric

TDI - HUNGER® 2PC URETHANE/PTFE ROD SEAL - METRIC

The TDI rod seal, manufactured by Hunger® has a urethane sealing lip with a BTFE insert secondary sealing lip. Under increasing pressure, the outer seal compresses the BTFE insert slide ring onto the rod. This unique seal creates a high force sealing edge with low-frictional resistance.

AS7 - 2 PC DOUBLE ACTING BTFE/NBR ROD SEAL

Our AS7 series rod seals are machined from bronze filled TFE for the most severe applications. Standard expander rings on this series rod seal are round cross section high memory 70 durometer nitrile; however, Viton expanders are available. Consult sales for pricing and delivery of special compounds. Temperature: -40° to 225°F Pressure: 0 to 5,000 PSI

CAT® 2 PC REPL STEPPED BTFE/NBR ROD BUFFER SEAL - INCH

CAT® - Type Stepped TFE Buffer Rings

AS2 - 2 PC STEPPED BTFE/NBR ROD BUFFER SEAL - INCH

Stepped seals are used to buffer pressure spikes from the primary rod seal, and are sometimes used in tandem. Combined with an unloaded u-cup, pressure builds between the step seal and primary seal and helps load the u-cup. Seals are machined from bronze filled Teflon®. Expanders are 70 durometer high memory nitrile, and are also available in Viton. Part numbers that contain a P63D suffix are made from 63D shore urethane. Temperature: -40°F to 225°F Pressure: 0 to 3500 psi

CAT®/CASE® 1 PC REPLACEMENT URETHANE BUFFER RING - INCH

These urethane buffer rings are rectangular shaped in profile. They are most commonly used in combination with a u-cup as a rod seal. Their purpose is to protect the rod seal from contaminants as well as to apply a hydraulic load to the u-cup. Some of these urethane rings are used as a backup ring combined with a rubber sealing ring in suspension cylinder applications. Part numbers starting with a G are used in Case® equipment; the others are typically used in Caterpillar® equipment. Temperature: -40°F to 225°F Pressure: 0 to 5000 psi

MBRU - 1 PC RECTANGULAR URETHANE BUFFER RING - METRIC

These urethane buffer rings are rectangular shaped in profile. They are most commonly used in combination with a u-cup as a rod seal. Their purpose is to protect the rod seal from contaminants as well as to apply a hydraulic load to the u-cup. Some of these urethane rings are used as a backup ring combined with a rubber sealing ring in suspension cylinder applications. Part numbers starting with a G are used in Case® equipment; the others are typically used in Caterpillar® equipment. Temperature: -40°F to 225°F Pressure: 0 to 5000 psi

CBR/CTB - CAT®/CASE® U-CUP BUFFER RING - INCH

U-cup type buffer rings are made in sizes to retrofit many Case® grooves, and are easy to install. They are designed for systems running high pressures or susceptible to pressure spikes. The sealing element is made from 90 durometer urethane and the anti-extrusion ring is made from POM. Metric sizes retrofit the stepped buffer ring grooves. Inch sizes below 2.25 do not have backup rings. Temperature: -22°F to 230°F Pressure: 0 to 5800 psi

MBR - URETHANE U-CUP STYLE BUFFER RING - METRIC

U-cup type buffer rings are made in sizes to retrofit many Caterpillar® and Case® grooves, and are easy to install. They are designed for systems running high pressures or susceptible to pressure spikes. The sealing element is made from 90 durometer urethane and the anti-extrusion ring is made from POM. Metric sizes retrofit the stepped buffer ring grooves. Temperature: -22°F to 230°F Pressure: 0 to 5800 psi

BU - 2PC URETHANE/POM ROD BUFFER SEAL W/BACKUP - METRIC

The BU is a compact, snap-in urethane rod buffer seal with a POM ID back-up ring. This seal is often found in heavy construction machinery cylinders. It was developed for high pressure loads and where extreme pressure spikes are common. Material: PU and POM. Temp: -30°F to +230°F Pressure: PSI 7200

SM - NITRILE/POM/NYLON 3 PC RIBBED ROD SEAL - METRIC

Our ribbed 3 piece rod seal is used as an alternative to veepacking in a rod application. This 3 piece seal offers excellent low pressure sealing due to its multi-lip NBR design. The header is made from POM and incorporates a nylon anti-extrusion ring which enables this seal to withstand up to 10,000 PSI. Temperature: -22°F to 248°F Pressure: 0 to 10,000 psi

MD - NITRILE ROD SQUEEZE SEAL w/POM BACKUP - METRIC

Style MD rod seals utilize a fabric reinforced rubber base combined with a POM backup for extrusion resistance, and a homogeneous nitrile sealing lip, enabling this seal to handle higher pressures than most other all-rubber seals. The squeeze design provides for good low pressure sealability. Temperature: -22°F to +248°F Pressure: 0 to 6000 psi
