Rectorseal 86687 Novent A2L Locking Cap 1/4 in Thread 2 Pack

Product Description

The RECTORSEAL 86687 is a Novent locking refrigerant cap designed to seal standard Schrader service valves on air conditioning systems that use A2L refrigerants. The red color coding identifies this cap as A2L-rated, helping technicians quickly distinguish it from caps used with other refrigerant classifications. The 1/4-inch thread fits standard Schrader valve stems. Requiring a special removal tool for both installation and removal, the 86687 provides a tamper-resistant barrier against unauthorized access, accidental refrigerant release, and cross-contamination from incorrect refrigerant charging. This product comes in a 2-pack. It is installed by licensed HVAC technicians during system service or commissioning.

This cap is intended for use on residential and light commercial A/C systems handling A2L mildly flammable refrigerants such as R-32 and R-454B, which are increasingly common in newer equipment. The locking design addresses code and manufacturer requirements for service valve protection on systems charged with A2L refrigerants. The embossed labeling and red color allow quick visual confirmation of correct cap type during inspection or service calls. Technicians working on new-equipment installations or retrofits will find this cap meets the access-control requirements associated with A2L refrigerant handling protocols.

Key Features

• Red color coding identifies A2L refrigerant service points at a glance
• Locks onto Schrader service valve with 1/4-inch thread — requires special tool for removal
• Embossed markings provide durable, permanent identification that does not wear off
• Tamper-resistant design reduces risk of accidental refrigerant release or unauthorized access
• Helps prevent refrigerant cross-contamination from incorrect charging
• Sold as a 2-pack for single-system or small-job use

Compatibility

Designed for use with standard Schrader service valves on A/C units and heat pump systems charged with A2L refrigerants, using a 1/4-inch thread connection.

Installation Notes

Installation and removal require the designated Novent special tool — standard valve cap drivers will not work and should not be forced. HVAC technicians should recover or isolate refrigerant per EPA Section 608 requirements before servicing valves on A2L systems. Because A2L refrigerants are mildly flammable, follow all applicable safety precautions and local codes when working on the system. Confirm the red A2L cap is matched to the correct refrigerant type before sealing the valve.
