VIDEO: Why Your Manway Gaskets May Be Non-Compliant

manway gasketsA few months ago, we talked about new railroad regulations that require shippers and terminals to take responsibility for manway NARs, or “non-accidental releases.”

In that blog post, we discussed how our partners at Parker sought out a sealing solution for manway gaskets that could eliminate the leading causes of NARs.

While we think it’s worth revisiting this important topic, we believe it’s also worth your time to watch the video from Parker that we’ve shared below. In this clip, the company explains how it reduces NARs with manway gaskets.

“Testing has proven that the Parker design maintained bolt torque within 1% of installations as compared to today’s typical seal designs that can lose bolt torque up to 20% of installation in a 24 hour period. This design feature is the first to allow a tanker manufacturer or maintenance facility the option to simplify design and speed securement without the worry of spills due to gasket relaxation or creep. The Parker design will work with today’s many nozzle and lid configurations, making it easy to convert current fleets.

Each manway nozzle gasket has product identification printed on an alignment tab to allow for full lot traceability. The printed identification includes codes for the material type, manufacturing shift and date. Parker’s internal rubber mixing capability ensures full traceability back to the raw ingredients used in production.

Parker can offer a wide range of elastomers to accommodate the various critical sealing challenges faced in rail transportation. Selecting a suitable material is critical to ensure long-term sealability. For aggressive chemicals, the addition of a PTFE over-molded film provides an extra layer of security, excellent chemical resistance, a wide service temperature and non-stick properties.”
