LB-RP series YKK fastex fastener features a comfortable shape and high tensile strength.
This fastex is ideal for life jackets (personal flotation devices). The 38mm size is UL listed (2F, 3F, 5H, and 5WV).
It has a simple side-opening design that allows one-handed operation and avoids accidental opening.
Fasteks LB-RP fits under the tape (sling) with a width of 25, 38 mm.
The range of application of fastex is quite wide. These can be: life jackets, backpacks, belts, bags and much more.
On the one hand (“mother”), this fastex has one slot through which it is sewn to the belt tape.
On the other side (“father”) of the fastex, there are two slots into which the belt tape is threaded with the possibility of adjustment.
Fastex material – acetal (ROM).
Acetal (Polyoxymethylene) is a crystalline thermoplastic polymer material that is characterized by excellent tensile strength, rigidity, surface hardness and chemical resistance.
Acetal has excellent flexural memory and retention of properties when subjected to repeated loading.
The physical properties of this plastic remain unchanged over a wide range of temperatures, relative humidity and weather conditions.
The normal short-term temperature range of its use is – 40° C to + 132° C.
The production of life jackets, professional camping equipment, and specialized gear places particularly high demands on plastic hardware. It must ensure a secure fit, withstand significant loads, and maintain stable operation even under difficult conditions. The YKK LB RP series fastener was developed specifically for these tasks. This model, part of the professional line of YKK plastic fasteners, is characterized by high strength, reliability, and compliance with the requirements for use in personal rescue equipment. Thanks to the use of modern materials and YKK’s proprietary engineering, the LB RP series is successfully used in both specialized gear and in hiking backpacks, bags, and other professional equipment.
What is the YKK LB RP series fastener?
The YKK LB RP series fastener belongs to the Side Release Buckle category—plastic fasteners with a side opening. The model’s key feature is UL certification for use in certain types of personal flotation devices (PFDs). This has made the series widely popular among manufacturers of specialized equipment where closure reliability is particularly important. The housing is made of polyacetal (POM), an engineering material with high mechanical strength and resistance to abrasion, moisture, and temperature fluctuations. This combination of materials ensures a long service life, even under intensive use.
This model is available for 25mm and 38mm webbing widths, making it suitable for both compact and professional equipment.
