Lucstar 195PCS A/C Seal Kit — O‑Ring & Sealing Washer Assortment, NBR for R‑134a with Hook Tool

Lucstar 195PCS A/C Seal Kit is a complete assortment of O‑rings, sealing washers and a pick tool designed to restore gas‑tight connections across vehicle air‑conditioning systems.

If you're servicing an automotive A/C system, having the right seals on hand speeds repairs and prevents leaks. This Lucstar kit bundles 90 O‑rings in 30 sizes plus 105 sealing washers across 12 common compressor and port dimensions, so you can match original parts and replace worn or damaged seals without multiple orders. The components are nitrile (NBR) rubber for broad compatibility with refrigerants, oils and fuels, and the included hook & pick tool helps retrieve and position small rings during installation.

What parts are included and how do they cover different vehicles?

The kit groups O‑rings and sealing washers by size and common compressor port references so you can find a match quickly. 90 O‑rings come as 30 sizes (3 of each), and 105 sealing washers include 12 models covering many compressor outlet and inlet fittings.

• 30 O‑ring sizes, three pieces per size for repeat repairs or spares
• 12 sealing washer models for common compressor ports, including Ford fitments
• Port references that align with typical R‑134a service fittings and compressor types
• Hook & pick tool to assist with removal and installation of small seals

How do the materials perform with refrigerant, oil and fuel exposure?

Lucstar uses nitrile (NBR) rubber for both O‑rings and washers, a material chosen for resistance to mineral oils, refrigerants like R‑134a, and many automotive fluids. While nitrile resists swelling and degradation from common A/C oils, always verify compatibility with specialty refrigerants or synthetic oils before extended use.

• Nitrile (NBR) construction for broad fluid resistance
• Suitable for R‑134a systems and conventional A/C lubricants
• Designed to resist oil, gasoline and water exposure during normal service
• Not intended as a chemical compatibility guarantee for every synthetic refrigerant

How does this kit simplify repairs and maintenance?

Keeping a comprehensive assortment eliminates downtime looking for the right size and lets you complete multiple repairs with one purchase. The organized set reduces trial fitting and the included tool speeds installation, especially in tight engine bay locations.

• Multiple quantities of each O‑ring reduce repeat ordering
• Sealing washers sized for common compressor ports and fittings
• Hook & pick tool improves access in compact spaces
• Plastic case or compartment organization (model dependent) for storage

Are these parts suitable for professional shops or DIY repairs?

The kit is sized and specified for both independent mechanics and knowledgeable DIYers who service automotive A/C systems. It supplies common replacement seals and washers useful for routine leak repair, compressor swaps, and line disassembly — though installers should follow OEM torque and service procedures.

• Professional-grade assortment used in maintenance and repairs
• Helpful for DIYers familiar with A/C diagnostics and safe handling
• Includes extras for inventory or multiple vehicles
• Does not replace the need for proper refrigerant handling equipment
