What are the main difference S between 471TC ST and 472TC hose?

What are the main difference S between 471TC ST and 472TC hose?

While Parker 471TC hose features an oil- resistant, Nitrile-based synthetic rubber tube, 472TC’s oil-resistant, synthetic rubber tube is high Nitrile to resist aggressive hydraulic fluids.

What is PKR rubber?

PKR rubber is one of the essential compounds for most industrial hoses because it withstands petroleum fluids. It also has the strength to hold up to weathering caused by air exposure. EPDM rubber is another essential compound in a vast range of industrial hoses.

What is minimum bend radius for hose?

The minimum bend radius formula is: L = A/360° x 2πr. Using this formula, the minimum required length of a hose can be determined for any situation. When calculating the length oa hose assembly, the length of the fittings must be considered.

What is the OD of 482TC 8?

Parker 482TC Hose Sizes and Specifications

Part No Inside Diameter Outside Diameter
482TC-5 5/16 0.59
482TC-6 3/8 0.69
482TC-8 1/2 0.82
482TC-10 5/8 0.94

What are the two basic types of hose covers?

Braided vs. Hydraulic hose can be referred to by construction style, of which there are two main types: braided and spiral. The majority of “low- pressure hoses” have a textile braided construction.

How do I know what size hydraulic hose I need?

To find out the hose size, check the layline. If the original printing has worn off, the original hose must be cut and the inside diameter measured. Be sure to measure the overall assembly length and fitting orientation before cutting the hose.

What does hose bend radius mean?

Bend radius: the radius of a bent section of hose measured to the innermost surface (R1) of the curved portion. Some manufacturers may measure to the centerline (R2) of the curved portion. Bend radius, static: the smallest radius at which a hose can be used without kinking while bent or flexed into a fixed position.

What is bend radius ratio?

The bend radius ratio b is defined as the ratio of the bend centerline radius, r, to the outer diameter of the pipe, D (see Fig. Context 2. the azimuth u is the angular coordinate of the damage in degrees (see Fig. 1(b)).

How do I know what size hydraulic fittings I need?

First you should determine the length of a hydraulic fitting by laying it on a table and then stretching your measuring tape across the top of it. Next, determine the outside diameter of the fitting by using your ID/OD calipers.

Which temperature ratings does Parker offer for its spiral hose offering?

However for water, water/glycol, and water/oil emulsion hydraulic fluids, the range drops to a rating of up to +185°F (+ 85°C). Air is rated even lower at up to 158°F (+ 70°C). Some media can increase or decrease the effects of temperature on the hose. The maximum rated temperature of a hose is specific to the media.

What do the numbers mean on a hydraulic hose?

Simply put, a dash size refers to an I.D. of a hydraulic hose or fitting in 1/16″ increments. For example, -6 hose would indicate a hose with I.D. of 6/16″ – or 3/8″. Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter.

What does 2 wire mean on hydraulic hoses?

Double wire braid hydraulic hose construction: It is made of synthetic rubber lining of oil resistant, two wire braid reinforcement separated by synthetic rubber layer, and synthetic rubber cover that is oil, fuel, weather and abrasion resistant.

What is the MBR of a hose?

An important measure of hose flexibility is the Minimum Bend Radius (MBR). While most everyone understands that this is the smallest radius to which a hose can be bent, the method of measuring this radius is often misunderstood.
