Which CAMLOCK sealing material does Tubes International offer?
NBR, EPDM, VITON, CR (neopren), PTFE/NBR, PTFE, EPDM, FEP/silikon, GYLON®
Can polypropylene CAMLOCK couplings be used at higher temperatures?
Yes. However, it is important to remember that a higher temperature will reduce the maximum allowable pressure of polypropylene CAMLOCK couplings. A rise in temperature to 70°C results in a 40% drop in pressure. For example, 3” CAMLOCK coupling made of polypropylene has the maximum allowable pressure of 4 bar at 20°C, but at 70°C [...]
Do I need any special tools to assemble or disassemble CAMLOCK couplings?
CAMLOCK couplings can be assembled with standard tools available in every workshop.
What are CAMLOCK couplings used for?
CAMLOCK couplings are intended for loading and unloading liquid materials.
What parameters need to be determined to select the right hose reel model for an application?
It is necessary to determine relevant operating conditions (medium, working pressure, working temperature), the technical parameters of a hose (not every hose, due to its design, is suitable for winding on a reel), the method of reel installation and the type of drive.
Can hose reels complete with hoses be used in potentially explosive areas?
Technically, it is possible to use a complete hose reel set in potentially explosive areas. The hose reel must be ATEX-certified and the hose wound on the reel must be approved for use in potentially explosive atmospheres. In addition, the elements used to install the hose on the reel must be made of non-sparking parts. [...]
Can hose reels complete with hoses be used for steam?
Hose reels can be used for steam, but only together with hoses specifically designed for steam. To mount the hose on the reel, always use fittings intended for steam, assembled with special safety clamps. The clamps should be checked for tightness with each use, as the hose material may deform when exposed to steam for [...]
What are the basic types of drives for hose reels?
Spring, hand crank and motor drives: electric, hydraulic and pneumatic.
Tapered or parallel thread fittings?
The vast majority of connections in pneumatics are made using fittings with BSP parallel threads and an O-ring seal. Unlike sealing by contact between threads, they do not require Teflon thread sealant, which could be a source of contamination for the pneumatic system. The exception is joining uneven (curved) surfaces where an O-ring may not [...]
Can push-in fittings work at pressures higher than 16 bar?
Yes. There are special "high-pressure" push-in fittings designed for lubrication systems, with working pressure of up to 30bar for air, and up to 150bar for lubricants.
