LSQ-PTR, Nitto Interchange, Flush Face Type Hydraulic Couplings in Carbon Steel, Chrome Six
Descripton:
LSQ-PTR Flat Face Type Hydraulic Quick Coupling(Steel)
Applications:SongQiao LSQ-PTR Series couplings are widely used in
the public utility market where hydraulic oil spillage can
constitute a serious safety hazard, particularly in overhead bucket
hoists that are used for maintenance of high-voltage power
transmission lines. These couplings are also used for quick change
of hydraulic Tools in construction, railway maintenance and mining
industries. The ease of cleaning makes them ideal for use in these
types of hostile environments.
Specifications:
| Body Size(in) | 1/4 | 3/8 |
| Rated Pressure(PSI) | 5000 | 5000 |
| Rated Flow(GPM) | 3 | 6 |
| Temperature Range(std seals) | -20℃ to +120℃ | |
| Spillage(ML)(max. per. disconnect) | .015 | .015 |
| Air inclusion(ML)(max. per connect) | .020 | .020 |
| Standard Seal | NBR | |
LSQ-PTR Features:
1. Sleeve locking mechanism is engaged by rotating sleeve after
connection. It prevents accidental disconnection when the coupling
is dragged along the ground.
2. Sleeve mechanism is designed to help prevent dirt from entering
the internal mechanism and thus causing faulty operation when
connecting or disconnecting. The sleeve covers the retaining ring
and also incorporates a dust seal in the spring area.
3. Steel construction, zinc plated with yellow chromate finish.
Hardened nipples and sleeves and solid barstock construction for
maximum resistance to damage from hydraulic and mechanical shock.
4. This Anti-Blowout Nitrile/PTFE bonded seals is designed to
prevent blow-out or damage during severe service conditions.
5. Durable ball-locking mechanism assures reliable connections,
every time. A large number of locking balls distributes the work
load evenly while providing alignment and swiveling action to
reduce hose torque and prolong hose life. CAUTION: These products
are not to be used as swivels. Rotation under pressure will result
in excessive and premature wear.
6 .LSQ-PTR Series couplings employ flush valving when connecting or
disconnecting. This means that the valves are mated together so
that only small amounts of fluid can be lost during disconnection
or air inclusion during reconnection.
7. Compatible with 350 Series of NITTO
Performance: Test Fluid:Oil-200SUS,1GPM=3.78L/Min,1PSID=0.0069MPa.
