NOVENT Multi-Key
The RectorSeal 86698 (also called “Novent Multi‑Key” or “Universal Locking Key”) is a tool used in HVAC / refrigeration systems to install and remove Novent locking refrigerant caps. These caps are placed over service valve Schrader ports to secure them against tampering, unauthorized access, or refrigerant theft or leakage. The locking caps can only be manipulated (installed or removed) using a specialized key. The 86698 version is a “multi‑key” intended to work with all Novent caps rather than a model‑specific key. It is targeted toward professional HVAC technicians, contractors, and service personnel working on air conditioning and refrigeration systems. The purpose is to provide a secure, tamper‑resistant closure of refrigerant service ports, while still allowing authorized service with the proper key.

A2L Tank Adapter
The Uniweld UA2LA is a brass tank adapter designed for connecting an A2L compatible gas cylinder (refrigerants/gases) to a regulator or hose with matching thread configurations. The adapter provides a transition between two thread types — female (LH) to male (RH) — facilitating use in refrigeration, HVAC, or gas-handling systems where A2L (lower flammability) gases are employed. In practice, it enables compatibility between gas cylinders and regulators or manifolds with differing thread standards, while maintaining leak integrity, durable materials, and safe operation in gas service. The adapter is offered by Uniweld as an accessory or spare component, and is also included as a bonus with certain A2L manifold assemblies.

Industrial Spray Adhesive
DP77 Industrial Spray Adhesive is a high-performance, multi-purpose adhesive designed for industrial and commercial applications where strong, long-lasting bonds are essential. It offers fast tack, excellent initial grab, and superior bond strength for a wide range of substrates including foam, fabric, insulation, plastics, metal, and wood. Its convenient spray format ensures even application and minimizes overspray, making it ideal for high-volume production environments as well as field installations. Commonly used in: HVAC duct insulation Upholstery and foam bonding Automotive interior assembly Laminate bonding Furniture manufacturing

36" Cable Ties
The 781889100882 cable tie is a self-locking, one-piece nylon strap designed to bundle and secure wires, cables, harnesses, or other components. It features serrated inner ribs and a ratcheting head mechanism that allows insertion but prevents backward movement, ensuring a tight, reliable hold. This product is suitable for both indoor and outdoor applications, with resistance to chemicals, UV light (if UV-stabilized grade), and variation in temperature. Typical uses include wire management in electrical panels, automotive wiring harnesses, HVAC systems, telecommunications, general industrial assembly, and more.

Twist-on Wire Connectors Orange
The DiversiTech orange twist‑on (a.k.a. screw‑on or wire nut) connectors are insulated caps designed to securely join two or more electrical conductors (wires) by twisting. They are color coded (orange in this case) to indicate their capacity (wire gauge range, number of wires) and voltage rating. You strip the wire ends, insert them into the connector, and twist the cap. Inside is a coiled spring (or metal insert) that grips and draws the wires together, ensuring both mechanical stability and electrical continuity. Orange connectors are commonly used for lighter gauge wiring (e.g. 22 to 14 AWG) in control circuits, lighting, or low-voltage applications where a compact, reliable splice is needed. The insulation shell is made of a thermoplastic material (high dielectric) and often includes a “deep skirt” design so that no bare wire is exposed. The shell is also designed to resist chemical attack (hydrocarbons, dilute acids or alkalis) in HVAC or industrial environments. 2jsupply.com +2 Baker Distributing +2 They carry UL and CSA approvals in many cases. 2jsupply.com +2 Baker Distributing +2 Some variants may include “winged” styles (wings molded on the shell) to provide better grip and easier turning in tight spaces.

Twist-on Wire Connectors Blue
The DiversiTech blue twist‑on / screw‑on wire connectors are small insulated caps used to join two or more electrical conductors (wires) safely. You strip the ends of the wires, insert them into the connector, and twist the cap, which causes an internal spring or coil to grip the wires and pull them together. These connectors are color coded (blue in this case) to indicate their capacity (wire gauge range, number of wires) and voltage rating. They are commonly used in HVAC, residential, and light commercial wiring tasks, especially for control wiring, thermostat circuits, low-voltage signals, or general electrical splices. They provide insulation, mechanical protection, and secure electrical contact without soldering or complex terminals. The blue connectors often have a “deep skirt” design so that no bare wire is exposed, and the thermoplastic shell is designed to resist chemicals (hydrocarbon vapors, dilute acids or alkalis) in HVAC environments. 2jsupply.com +2 SupplyHouse.com +2 Some variants include “winged” designs (molded wings or tabs) to improve grip and twisting leverage, especially helpful when working in tight spaces or with more rigid wires.

11" Cable Ties
These are self‑locking nylon “zip ties” designed for bundling and securing cables, wires, pipes, or other grouped items. The black (UV) version is intended for both indoor and outdoor applications, where exposure to sunlight or UV radiation may occur. They come in packs (e.g. 100 per pack) and include a resealable bag. The Home Depot +2 homedepot.ca +2 The head of each tie contains an internal ratcheting mechanism (serrations) that allows the tail to be inserted and locked in place, preventing loosening. The design aims to balance a low insertion force (easy to thread) with sufficient holding strength. homedepot.ca +1 These are often UL 21S rated (for supporting cables) and meet industry standards for standard nylon cable ties. The Home Depot +1 They are commonly used in electrical, telecommunications, HVAC, construction, or general bundling tasks.

LINE SET COVER MINISPLIT 3'
An Everwell line set cover is a decorative, protective enclosure used primarily in HVAC (mini-split or ducted split) installations. Its purpose is to conceal and protect exposed refrigerant piping, electrical wiring, and condensate/drain lines from the elements, while giving the installation a cleaner, more finished aesthetic. The cover is made of durable plastic materials that are weather-resistant and UV-stabilized, and typically comes as a modular kit including straight sections and fittings (elbows, joints, end caps, etc.). The cover pieces snap together over existing lines (or can be installed before lines) and may be paintable to match the surrounding wall.
