The OETIKER 15300008-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from stainless steel, this clamp installs with a pincer tool that deforms the ear and locks the clamp in place with no loosening over time. The nominal size is 5/16 inch, with a clamping range of 6.80 to 8.00 millimeters. Band width is 0.197 inches and band thickness is 0.020 inches. Licensed plumbers, HVAC technicians, and refrigeration mechanics rely on this style of clamp where a tamper-evident, vibration-resistant connection is required.
This clamp is suited for residential and light commercial installations involving small-diameter hose and tubing, including PEX connections, condensate drain lines, coolant hoses, and similar low-pressure fluid transfer lines. The 5/16 inch nominal size fits tubing in the 6.80 to 8.00 millimeter outside diameter range. It is commonly specified where a one-time, non-adjustable clamp is preferred over a worm-drive or T-bolt style clamp.
Designed as an OEM-style 1-ear stepless clamp for small-diameter hose and tubing connections in plumbing, HVAC, and fluid-handling systems requiring a 5/16 inch nominal clamp size.
Installation requires an ear-clamp pincer tool rated for 1-ear stepless clamps. Ensure the hose or tubing is fully seated on the fitting before crimping. Once the ear is deformed, the clamp cannot be reopened or reused. Shut off fluid supply and relieve system pressure before servicing any connection point.
