Seal-Lok Features
Table A4 — Seal-Lok Features, Advantages and Benefits
Feature Advantage Benefit
Conformance to SAE J1453
and ISO 8434-3
Versatility for end user and customer
standardization efforts
Standardization reduces procurement
costs.
Elastomeric seal Tolerant of surface imperfections to
provide leak-free connection
Reduces operational and
maintenance costs
High pressure rating Good for wider range of applications,
providing opportunity to standardize
Standardization reduces procurement
costs
No tube entry (flat-face design) Easy and fast drop-in installation Saves assembly and disassembly
time
Captive O-ring groove (CORG) Prevents O-ring fall-out to ensure positive
and leak-free connection
Redues operational and maintenance
costs
Forged Shapes Higher resistance to mechanical shock
and vibration that can lead to leakage
Reduces operational and
maintenance costs
Similar envelope size to 37°
flared fitting
Minimizes re-design of hydraulic systems Reduces re-design costs
Wide tube wall range (no
wall thickness limitation for
braze method; however,
recommended min/max ranges
are shown on page A7)
Allows for greater flexibility in design of
hydraulic system
Reduces design costs
Resistance to over-torque Minimizes damage during assembly Reduces operational and
maintenance costs
Unlimited reusability/
remakeability
Extends the service life of the fitting Reduces maintenance costs and
component replacement costs.
Parflange method of assembly Several times faster than brazing/welding Reduces assembly cost
No special pre- and post-braze welding
cleaning
Reduces tube preparation cost
No open flame or heat source required Improves operator safety
No braze joint or potential leak path Reduces operational and
maintenance costs
