The Viega Compact Angled PEX Crimp Hand Tool is a specialized instrument designed for creating secure, full-circle crimp connections in PEX tubing systems. Its primary function is to join PEX tubing with manufacturer-approved crimp rings and fittings, ensuring a leak-free and robust connection. This tool is specifically engineered for use with copper crimp rings made to ASTM F1807, F2159, and brass, copper, or plastic fittings for ASTM F876/F877 SDR9 PEX tubing. It can also be utilized for crimp connections with PB tubing and corresponding rings and fittings.
The core function of the Compact Angled PEX Crimp Hand Tool is to apply precise and consistent pressure to a copper crimp ring, deforming it around a PEX fitting and tubing to create a permanent seal. The tool operates by closing its jaws around the crimp ring, compressing it uniformly. This compression process ensures that the crimp meets the dimensional requirements of ASTM F1807, F2159, F845, or F1380 fitting standards, which are critical for the integrity of the plumbing system. The tool is designed to produce a single, proper crimp, and users are explicitly cautioned against crimping twice, as this can compromise the connection. The angled design of the tool likely facilitates access in tight spaces, enhancing its versatility in various installation scenarios.
The tool's operation involves a straightforward, multi-step process. To begin, with the pipe, fitting, and crimp ring in their assembly position, the user pulls back on the upper, moving handle to open the jaws fully. The jaws are then positioned carefully around the crimp ring. Gentle release of hand pressure on the moving handle allows the jaws to close properly and squarely over the crimp ring, ensuring correct alignment. The final step involves firmly pressing the handles together to complete the crimp. A critical aspect of its usage is the requirement for a proper, single crimp; repeated crimping is explicitly prohibited.
Post-crimp, it is essential to verify the quality of the connection. Completed crimps must adhere to specific dimensional requirements, which can be checked using a Crimp Caliper (Viega stock code 53507) or another suitable measuring device. The measurement should not be taken at the "scared" (jaw overlap point) portion of the ring. If the "GO" side of the gauge does not fit over the ring, it indicates an under-crimp, necessitating the removal of the connection, replacement of the fitting and crimp rings, and adjustment of the tool. Conversely, if the "NO GO" side fits over the ring, it signifies an over-crimp, requiring the same corrective actions. This rigorous checking process underscores the importance of precision in every crimp.
The tool is user-adjustable, allowing for recalibration if it begins to produce unsatisfactory crimps. This adjustment involves a specific procedure: noting the number on the hex head of the back pin, carefully removing a retaining clip, pushing the back pin to clear the tool body, rotating the pin to a higher number to reduce crimp size, pushing the pin back, and replacing the retaining clip. After adjustment, a test joint must be crimped and checked for proper sizing. This adjustability ensures the tool's long-term accuracy and performance, even with wear over time. Users are advised to refer to the fitting and tubing manufacturer's product assembly instructions for specific joining and gauging procedures.
Proper maintenance is crucial for extending the life of the Compact Angled PEX Crimp Hand Tool and preserving the quality of its crimps. The primary maintenance task involves frequently lubricating the pivot points with light oil. This lubrication ensures smooth action of the handles and jaws, contributing to maximum tool life and consistent crimp quality. The manual explicitly states that users should not attempt to repair the tool themselves, directing them to contact Viega for any tool-related information or issues.
Beyond lubrication, the tool requires regular checks for correct adjustment. It is recommended that the Compact Angled PEX Crimp Hand Tool be checked for proper adjustment at the start of every day. Furthermore, each crimp ring should be gauged to ensure it has been crimped properly and to verify the accuracy of the tool. The dimensional accuracy of the Crimp Caliper itself can degrade due to normal field wear and tear, necessitating regular checks with a suitable measuring device or replacement with a new gauge to maintain measurement accuracy. These routine checks and adjustments are integral to ensuring the tool consistently produces reliable crimps and maintains its operational integrity over time. The tool is covered by a limited warranty for ninety days from the date of purchase, emphasizing the importance of proper usage and maintenance to ensure warranty availability.
