GUIDES · ASBESTOS MATERIALS

Asbestos Gaskets, Rope & Seals.

Inside older boilers, pipe flanges, ovens and industrial plant sit thousands of asbestos gaskets and rope seals, invisible until something is opened up.

Where you'll find them

Flange joints on heating and process pipework, boiler and flue seals, oven and kiln doors, pumps and valves in any plant installed before the mid-1980s.

The risk

Sealed in service they’re dormant; cracking a flange or stripping a boiler disturbs them. Maintenance teams need them on the asbestos register so no one opens a joint unaware.

Removal and cost

Usually handled as controlled non-licensed work during maintenance or decommissioning, wetted, removed intact and bagged at the joint. On strip-outs and demolition we sweep plant for gaskets as standard. Figures are industry guide rates, not Innov8 Group prices, we're typically cheaper. Contact us for an official quotation.

Small parts, wide spread

Compressed asbestos fibre (CAF) gaskets, rope seals and packing were the default jointing materials for most of the twentieth century: pipe flanges, boiler doors, flue joints, pump housings, valve glands, even domestic back boilers and solid-fuel stoves. Individually tiny, they are everywhere in pre-2000 plant — a single boiler house can hold hundreds. Manufacture and supply were banned in 1999, but anything installed before then is legitimately still in place and still turns up daily in maintenance work.

The maintenance-fitter risk

A bolted CAF gasket in service is low risk. The exposure happens at strip-down: breaking a flange, scraping or wire-brushing the old gasket off the face, or re-packing a valve — jobs fitters have done bare-handed for decades. Scraping a bonded gasket dry turns it to dust at face height. Under CAR 2012 most gasket work is non-licensed or NNLW, but it still requires trained operatives, wet methods, RPE and consigned disposal — and a written risk assessment before the spanner comes out.

Surveys, shutdowns and plant strip-outs

On industrial sites, gaskets and seals are exactly what a refurbishment and demolition survey exists to catch before a shutdown or strip-out. We inspect, sample and remove asbestos jointing as part of wider industrial decommissioning — flange by flange where plant is staying, or wholesale where it is coming out. If your fitters have already disturbed old gaskets, our disturbed asbestos guide covers the immediate steps.
FREQUENTLY ASKED

Common questions

Where are asbestos gaskets and seals found?
In flanged pipe joints, boilers, pumps, valves and old plant across industrial sites — plus rope seals around boiler and flue doors in commercial and domestic settings. Any plant installed before 2000 can still carry them.
Can maintenance staff replace asbestos gaskets?
Removing a compressed asbestos fibre gasket intact is defined lower-risk work with the right training and controls, but scraping, wire-brushing or grinding old gasket faces is not — that’s where fibre release happens. When in doubt, hand it to us.
Do gaskets need to be removed before plant is scrapped?
Yes — plant going for scrap or refurbishment should have asbestos gaskets, ropes and seals identified and removed first, with consignment notes to match. We strip them as part of decommissioning works.
