A hose repair kit includes a retaining sleeve having a first opening to receive an end of a hose. There is a swivel coupling inserted into a second end of the hose retaining sleeve to engage with the hose. The swivel coupling includes a first annular member with an annular barb at one end and a socket to receive a key at a second end. There is an annular retaining ring groove with a retaining ring therein. A second annular member receives, within an internal bore having an annular recess, the first annular member and the retaining ring engages the annular recess to secure the first annular member to the second annular member. The surface of the bore is frusto-conically shaped allowing the retaining ring to be compressed as it travels into the bore until it reaches the annular recess and expands into and is seated in the annular recess.

An apparatus for protecting a tubing from a moving object includes a housing and a hooking member. The housing includes an exterior surface and a passage. The passage is configured to receive the tubing, and extends from a first end to a second end of the housing. The hooking member extends from the exterior surface of the housing, and is configured to catch onto the moving object to protect piece of tubing.

Disclosed herein is a hydraulic brake system. The hydraulic brake system comprises a damping device configured to attenuate pressure pulsation of brake oil discharged according to a driving of a pump, wherein the damping device includes a sleeve fixed to a bore that is connected to a discharge end of the pump and having an opened one side, a damping piston slidably installed inside the sleeve, and an elastic member provided inside the sleeve and configured to elastically support the damping piston, and wherein a slot having a width which is varied is formed at an inner circumferential surface of the sleeve in a direction in which the brake oil flows so that a variable orifice is formed between the damping piston and the sleeve.

A master cylinder for a hydraulic brake or clutch system, in particular, a handlebar steered vehicle, in particular a bicycle, comprises a housing containing a cylinder chamber, in which are disposed a piston slidable therein and a pressure chamber. A compensation chamber is connected with the pressure chamber through at least one compensation bore. Also provided is a cover closing the housing and a counterpart for mounting the master cylinder on a handlebar tube. Further provided is at least one connecting device for connecting the counterpart with the housing of the master cylinder. Included with the connecting device is a first connecting portion for connecting the cover with the housing of the master cylinder and a second connecting portion for connecting the counterpart with the master cylinder and for mounting the master cylinder on a handlebar tube.

An elastic seal element seals a fluid passage between a first component and a second component from the surroundings, the fluid passage passing through the seal element. The seal element has a first bead, which provides a sealing line to sealingly contact the first component around the fluid passage. The seal element further has a second bead, which provides a second sealing line to sealingly contact the second component around the fluid passage. The seal element has a tubular shape, a tubular casing extending between the first bead at the first end of the seal element and the second bead at the second end of the seal element, wherein the tubular casing allows a transversal offset of the second bead relative to the first bead to seal the fluid passage by the seal element even when the second component is offset transversely relative to the first component.

A protective cap is provided for protecting an end portion of a hydraulic hose of a hydraulic bicycle component. The protective cap is configured to be removably coupled to the end portion of the hydraulic hose. The protective cap comprises a head portion and a cord attachment portion. The cord attachment portion has a through hole for attaching a cord to the protective cap.

A steering knuckle for a vehicle wheel includes a wheel connection section, an upper steering attachment section, and a lower steering attachment section. The wheel connection section is configured for connecting the steering knuckle to the vehicle wheel. The upper steering attachment section is configured to provide a connection of the steering knuckle to a steering drive. The steering knuckle is intended to permit wheel-specific steering with a large steering angle and, at the same time, to support the integration of other vehicle wheel components. The upper steering attachment section, the wheel connection section, and the lower steering attachment section together delimit a recess on at least three sides such that a connector section arranged in the wheel connection section delimits an inner end of the recess and is configured for guiding at least one line through the recess.

A semi-truck to RV conversion device and system is disclosed. The device has a weatherproof electrical enclosure mounted on a semi-truck, which can be attached permanently or removably via, for example, an adjustable strap and fastener. The conversion device features gladhands for connecting to the truck's air lines, a semi-truck light cord plug-in, and an RV-style light cord plug-in for integrating the truck's lighting system with the trailer. The system also incorporates an air-to-electric brake controller that converts air pressure from the truck's braking system into electrical signals to control the trailer's electric brakes, with the braking force on the trailer being proportionate to the air pressure signal for synchronized braking. This system improves safety and enables for quick transitions between hauling different types of trailers.
