M18x1.5 TR21-4 Thread CO2 Cylinder Refill Adapter Soda Cylinder Valve Suitable for Sodastream Bottle Connect to Co2 Cylinder

Product Information

Corrosion-Resistant:The surface is electroplated, as a mirror, corrosion-resistant, not easy to oxidize and rust. This eliminates the need for brakes or other holding devices to sustain loads after they have been positioned. One such standard is the German Metrisches ISO-Trapezgewinde DIN 103 which has been adopted by the International Organization for Standards (ISO). Sometimes misnamed "metric Acme" or "metric M series Acme"

where Tr designates a trapezoidal thread, 8 is the nominal diameter in millimeters, and 1.5 is the pitch in millimeters. When there is no suffix it is a single start thread. If there is a suffix then the value after the multiplication sign is the lead and the value in the parentheses is the pitch. For example: Trapezoidal threads are defined as follows by ISO standards: ISO 2901, ISO 2901, ISO 2903, ISO 2904 and ISO 103. Gages ISO metric trapezoidal screw thread are defined in the DIN 103-9 . Dimensions shown are in mm, if you wish to convert to Inches, please use our universal converter. Trapezoidal Thread Information Trapezoidal threads are codified by DIN 103. Although metric screw threads are generally more prevalent worldwide than imperial threads, the Acme thread is very common worldwide, and may be more widely used than the trapezoidal metric thread.TR 60 x 18 (P9) LH would denoted two starts, as the lead divided by the pitch is two. The "LH" denotes a left hand thread. Dimensional Charts relating to Trapezoidal Threads from 8 - 95mm, 100 - 195mm, 200 - 295mm, 300 - 560mm and 600 - 1120mm. Uses: The adapter is mounted on the TR21-4 threaded soda machine cylinder to act as a conversion interface

Trapezoidal lead screws look like Acme screws and have the same stout thread form and the same robust and durable features as the Acme series. Trapezoidal lead screws and nuts are power transmission screw threads similar to the Acme series but made to metric dimensions and standards. Practical & Convenient to Use:Good sealing performance, no air leakage when connected with the cylinder, more convenient to use. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Practical & Convenient to Use:Good sealing performance, no leakage when connected with the cylinder, more convenient to use.

Common Issues When Refilling SodaStream Cylinders

Low lead angles offer a high mechanical advantage for Trapezoidal screws. This means they require less input torque for a given load than other power screws.
