Daptemn A/C Compressor Sealing Washer and O-Ring Kit 175 PCS — Metal Gaskets & NBR O-Rings, Assorted Sizes

Whether you’re a DIY mechanic or a professional technician, this kit gathers varied sizes of self-centering compressor gaskets and multiple NBR O-ring diameters to help repair common A/C leaks without ordering single pieces. The set combines corrosion-resistant gasket plates and oil-compatible NBR elastomer rings rated for wide temperature and pressure ranges, making it suitable for typical automotive A/C systems and related sealing tasks.

Which components are included and why do they matter?

The kit contains both thin stamped metal gaskets in multiple inner/outer diameters and a broad selection of NBR O-rings in assorted cross-sections. Having matched gasket and O-ring sizes on hand reduces downtime when replacing compressor ports, service valves, or threaded plugs.

• 175 total pieces: a mixture of self-centered metal compressor gaskets and NBR O-rings in varied diameters.
• Gaskets sized across common compressor ports (several ranges around 8–31.5mm IDs).
• O-rings provided in many metric sizes and cross-sections for valves, fittings, and hose ends.

How durable are these gaskets and O-rings for automotive A/C use?

Gaskets are manufactured from a plated, rust-resistant metal; the O-rings are NBR (nitrile) formulated for compatibility with oil and refrigerant environments. The materials are chosen to resist oil, pressure, and wear found in air-conditioning compressor circuits, providing a longer service life than cheap alternatives.

• Metal gasket finish resists corrosion and maintains shape under torque.
• NBR O-rings compatible with common refrigerant/oil media and temperature swings.
• Working temperature range supports typical automotive conditions from cold starts to hot engine bays.

Will this kit fit my vehicle, and what systems can it service?

The assortment is intended to cover many compressor port sizes used on models from about 2000–2015 across popular brands. It’s designed for compressor repairs, service port maintenance, threaded plug sealing, and other small hydraulic or pneumatic sealing jobs where oil or similar fluids are present.

• Compatible with many domestic and import vehicles including common makes from the 2000–2015 era.
• Useful for compressor ports, service fittings, threaded joints, and related sealing tasks.
• Also applicable to non-A/C oil-based systems or mechanical joints requiring durable gaskets.

How should I choose the right size and install these parts?

Select the metal gasket or O-ring that matches the compressor port inner and outer dimensions, or the thread/plunger diameter you’re sealing. Clean mating surfaces, inspect for damage, and replace any deformed components; ensure proper torque and seating to avoid blowouts or leaks.

• Measure port IDs/ODs or existing seals before selecting a replacement from the kit.
• Clean surfaces of old gasket material and debris to ensure a flat seating surface.
• Lubricate O-rings lightly with compatible oil to ease installation and prevent twisting.

This Daptemn kit is for vehicle owners, fleet technicians, and independent mechanics who want a ready stock of compressor gaskets and O-rings to speed repairs and lower parts wait time. If you service A/C compressors, perform seasonal maintenance, or restore older systems, this assortment reduces trips to specialty suppliers and helps you complete jobs with the correct sizes on hand.
