1. Product Advantages
Superior Protection: Adopts a double-lip all-rubber structure to block 99% of external contaminants (dust, sand, debris), preventing hydraulic cylinder internal wear and reducing maintenance costs by 30%.
Dual Material Options: Nitrile Rubber (NBR) for excellent oil/wear resistance (-35℃ to +105℃); Fluororubber (FKM) for high-temperature/chemical resistance (-10℃ to +150℃), meeting diverse industrial needs.
Stable Performance: Withstands ≤150bar pressure and ≤2m/s reciprocating speed, ensuring long-term reliability even in harsh working conditions.
Easy Installation: Directly fits into integrated grooves, no extra tools required—cuts assembly time by 50% compared to traditional seals.
2. Working Principle
The LBH dust seal forms a "double defense line" via its dual lips:
Outer Lip: First barrier to block large particles (e.g., sand) from contacting the hydraulic rod.
Inner Lip: Secondary seal to trap tiny dust and prevent residual oil leakage, while the all-rubber structure maintains tight contact with the rod surface, avoiding contaminant penetration.

Plastic machinery (injection molding machines)
5. FAQ
Q1: How to choose between NBR and FKM materials?
A1: Choose NBR for general oil-based hydraulic systems; FKM for high-temperature (＞105℃) or chemical-exposed environments (e.g., petrochemical plants).
Q2: What is the service life of the LBH dust seal?
A2: Under normal use, NBR seals last 18–24 months; FKM seals last 24–36 months (varies by working conditions).
Q3: Does Forever Seals provide after-sales support?
A3: Yes—we offer 12-month warranty, technical consultation, and replacement service for quality-related issues.
