Apart from excellent high-pressure performance, the multispiral hose and fittings offer following advantages:

• Specially engineered shells guarantee optimum compression and grip of the fitting on the hose No-Skive design eliminates the need to remove the hose cover before crimping
• We deal in these hoses that are manufactured from a single piece of steel, Parker monobloc fittings eliminate potential leak paths
• The hose range is available with high abrasion resistant TC or ST covers, prolonging hose life.
• Low volumetric expansion at maximum working pressure.
• Wide fluid compatibility.
• As the hydraulic market moves towards higher working pressures and flow volumes, multispiral hoses are playing an ever increasingly important role in machine design.
• Parker, as the worldwide market leader in No-Skive hose technology, meets these requirements by offering a full range of No-Skive multispiral hose and fittings up to 42,0 MPa.
• The range covers hoses according to ISO, EN and SAE standards in sizes from -6 up to -32 and is accompanied by a full range of matching one-piece monobloc fittings manufactured from high-grade steel.
• All hose and fitting combinations are thoroughly tested and approved according to Parker standards that exceed those of internationally accepted bodies such as ISO.

Application:

• Petroleum or synthetic hydraulic fluids in hydraulic systems
• Machine tools
• Hydraulic tools
• Clamps and
• Gas applications.

Design and Construction z
Parker O-Lok fittings can be assembled either by orbital flanging of the tube using the Parker Parflange process or by brazing a spud on the tube end.

Flanging
Preparing the tube end using the Parker Parflange process provides the user with the means of easily achieving a leak-free connection. It is ideal for in-house or on site applications.

Brazing
An alternative solution is to assemble Parker O-lok Fittings using a brazing spud on the tube end. Brazing can be useful for field assembly or when small quantities of tubes are being prepared.

EITHER CASE
In both cases the tube end plus sleeve or spud acts as a reinforced point to provide higher vibration and impulse resistance. Parker O-Lok fittings consist of Fitting body, Sleeve, O-ring and Nut.

The Parker O-Lok Body
There are over 30 different body shapes to choose from when specifying Parker O-Lok fittings for your application. The body face has a machined groove which contains an O-Ring.
Parker O-Lok shape fittings are manufactured from forgings for greater strength and longer service life.

The Parker O-ring
A 90 degree Durometer Shore Nitrile O-ring is held captive in the groove of the fitting body. Note that Nitrile O-ring can be replaced by other O-ring materials.

Captive Groove Design
The O-ring groove incorporates an overhang to retain the O-ring in position, helping to eliminate O-ring loss or disturbance during tube assembly. This feature is now standardized under SAE J1453 as an alternative groove design.

The Parker O-Lok Sleeve
Mechanical sleeve
During the 90 degree flanging operation, the tube is pressed against the inner surface of the Parflange Sleeve, providing high rigidity when assembles to the fitting. Each Parflange sleeve is manufactured to strict tolerances and marker Parflanhe ensuring you of the highest quality assembly.
Brazed sleeve
Parker also manufactures spuds that can be brazed onto the tube. Reducing spuds allow Downsizing a large tube end to a smaller one.

The Parker O-Lok Nut
Parker O-Lok fitting nuts are cold formed (smaller sizes) or hot forged (larger sizes), depending on size.

Parker O-Lok Finish
Parker P-Lok steel fittings are yellow zinc plated (thickness 8 to 14um). This plating gives a high corrosion resistance (350 hours salt spray test to red rust*).
*Test in accordance with ASTM B117 or NFX 4.1.002.

Soft-Seal Capability
The design of the Parker O-Lok fittings used with the parflange flanging system gives only one leak path which is sealed by a standard shore a Nitrile O-ring.

Reusability/Remake
Parker O-Lok fittings can be assembled and disassembled many times. It is recommended that the O-ring is replaced to ensure a perfect assembly.

Features:

• These Triple-Lok fittings are manufactured in steel, 316 stainless steel and brass for optimum fluid compatibility and corrosion resistance.
• Available sizes range from 1/8" tube O.D. to 2" tube O.D. in several configurations. Adaptability to global ports is another key benefit of Triple-Lok. (Standard ports include: SAE, straight thread ISO-6149, NPT, BSPT, BSPP and DIN.)
• The Triple-Lok tube fitting is also readily available for metric tubing and hose adapter applications
• Simply by changing the industry standard sleeve, the same Triple-Lok body can be adapted to metric tubing in sizes ranging from 6 mm tube O.D. to 38 mm tube O.D.
• Likewise, by using only the body without the nut and sleeve, the Triple-Lok fitting is used as an industry standard hose adapter.
