Solid Teflon backup ring with a flat cross-section.
PTFE can withstand high temperatures and is compatible with nearly all fluids.
- High temperature range
- Deals very well with surface wear
A heavy duty double-acting assembly, the capped piston T-seal exhibits excellent sealability, extrusion resistance, and wearability. T-seals with “BR” suffix utilize a Bronze Filled PTFE cap instead of the standard Glass Filled PTFE cap.
PTFE; Nylon; Rubber Material | 10.275 in Nominal Inner Diameter | Capped Piston T-Seal
Features
- Glass-filled PTFE cap, nylon back-up, rubber energizer
These lip-type buffer seals are designed for replacement in Caterpillar® cylinders. The hinged-lip design reduces friction, heat, and wear under low-pressure conditions and acts as a check valve allowing back-pressure relief. Seals for rod sizes 2-1/8” and under do not have a back-up ring.
Urethane Material | 2 1/8 in Nominal Inner Diameter | Buffer Seal
Used interchangeably for piston or rod sealing, these u-seals employ the same tough urethane material found in our, Heavy Duty Rod and Piston U-Seals.
92A Durometer | Urethane Material | 3 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal
1.75 in clevis pin with two 0.173 in holes that can be used to retain the pin with cotter pins or locking pins. Cotter pins not included.
Threaded at the base with a pin hole inside of the spherical bearing. Order to fit piston rod thread size.
This U-cup style buffer ring offers an asymmetric sealing lip profile, chamfered sealing edges, and pressure relieving capabilities to prevent inner pressure entrapment when employed in a tandem sealing system. This rod buffer seal is designed to absorb impact pressure fluctuations under high-load conditions thus increasing the life of the primary seal.
Urethane Material | 1 3/4 in Nominal Inner Diameter | Buffer Seal
Suffix “V” designates fluorocarbon material,“N” designates nitrile material, and “HT” designates high temperature urethane.
