Gas Equipment Knob-Type Interface

The Gas Equipment Knob-Style Interface is a user-friendly, secure connection component designed to link gas sources (e.g., cylinders) to appliances, merging intuitive operation, leak-proof performance, and durable construction for residential and commercial gaseous fuel systems.

This interface’s core strengths lie in its simplicity and reliability: its knob-style design enables tool-free, hand-tightened connections—no complex threading or extra tools required—making it accessible for all users. The brass and reinforced plastic build ensures compatibility with propane/butane and resistance to corrosion, while its integrated sealing mechanism eliminates gas leak risks, a critical safety priority. Its compact, ergonomic layout fits tight spaces (e.g., behind appliances or around cylinder setups), and it requires minimal maintenance (only visual inspections), supporting long-term practicality.

Structurally, the interface consists of a ribbed black plastic knob (for non-slip grip), a brass connection core (with precision internal components), and a protruding brass pin (for secure appliance engagement, visible in the image). The ribbed knob provides leverage for easy tightening/loosening by hand, while the brass core delivers durability and gas compatibility. The internal sealing gasket creates a hermetic seal when the knob is tightened, and the brass pin aligns with appliance ports to prevent accidental disengagement. Reinforced joints distribute pressure evenly, and the compact profile maintains space efficiency in gas setups.

This knob-style interface is widely used in residential outdoor setups (e.g., patio grills, portable heaters), commercial food service (e.g., countertop grills, catering warmers), and small-scale industrial gas tools: in homes, it links propane cylinders to backyard cooking appliances; in small businesses, it connects gas sources to compact food preparation equipment; in workshops, it fits portable gas-powered tools. It is particularly suitable for environments where quick, user-friendly connections are priorities (e.g., residential kitchens, food trucks). Whether used with propane or butane systems, this interface delivers consistent, safe performance. It provides a hassle-free, safety-focused connection solution, balances convenience and durability, and meets the needs of homeowners, small business operators, and tradespeople seeking a robust gas equipment interface.
