A sealant gun inspection record is a short written check of the gun, hose, fittings and pressure response, completed before and after each job. Log the date, equipment identity, condition of seals and hoses, the product injected, the quantity, and any abnormal pressure response. Review the log at intervals your site rules set, and stop work when a check fails.

An inspection log for injection equipment
A simple inspection log keeps your sealant guns safe, serviceable and ready for online valve work.
1. What the inspection log records
An inspection log turns routine checks into evidence. It takes minutes per job, and it protects the operator, the gun and the valve. Keep it with the gun, on paper or in a simple spreadsheet.
- Date, site and permit reference for the job.
- Equipment identity: gun model, hose and pump where used.
- Condition of seals, couplings, hose and buttonhead fittings before use.
- Valve tag, service and the product injected, with the quantity.
- Pressure response observed during injection, and any stop-work events.
- Operator name and the date of the next inspection.
Record what you saw, not what you assumed. A rising pressure reading indicates a blockage; it does not confirm one.
2. Inspection frequency by use
Frequency should follow how hard the equipment works. A gun in daily service needs closer attention than a gun used occasionally. Common practice follows the pattern below, adjusted to site rules and maker guidance.
- Before every job: a visual check of hose, fittings and couplings, plus a function check on a test connection.
- After every job: clean the equipment, inspect for damage, and log the products and quantities used.
- After heavy use or a long campaign: a fuller strip and inspection, using the service kits made for your gun model.
- At planned intervals: a documented review, even if the gun has stayed on the shelf.
Idle equipment still ages in storage. Seals dry out and hoses degrade, so log stored guns as well as working ones.
3. How the log supports safe injection
The log is a safety document, not just paperwork. It catches wear before it becomes a hazard under pressure. High pressure equipment fails in unforgiving ways, and the record is your early warning.
Injection work has gates. The fittings must be in good condition, the valve design must suit injection, and the permit must allow the job.
Treat certain entries as stop-work triggers: damaged hose covers, weeping couplings, deformed fittings, or pressure that climbs without product movement. Stop, tag the gun out of service, and record the finding.
Stay within the ratings of the gun and the fitting, and watch the gauge. Our pages on high pressure gun safety rules and injection pressure versus line pressure give the detail.
4. Turning records into decisions
Logs only help when someone reads them. Look for patterns across jobs: the same fitting weeping, the same gun losing pressure, the same product used too often. Patterns point towards repair, spares or training.
When records show wear, act early. Hold the right kits and seals, as described in our advice on spares to hold for injection equipment. For guns needing more than a kit, our equipment repair service returns them to a known condition.
Care between jobs matters too. Our guidance on keeping sealant guns reliable covers cleaning and storage that reduce the repairs you need.
5. Reviewing the log
A log no one reviews is just a notebook. Plan the review alongside your maintenance schedule, and involve the operators who write the entries. They often notice what the paperwork misses.
- Check that every job has a complete entry, including stop-work events and quantities.
- Compare product use across valves to spot changing seat or seal conditions.
- Flag repeat faults, and decide on repair, spares or replacement.
- Set the next review date, and sign the record.
A reviewed log also supports audits and incident investigations. It shows a pattern of care, and it gives evidence when a valve's history is questioned.
6. Starting your log with BTR VSI
If you are building an online valve maintenance capability, start the log on day one. Our injection equipment buying guide explains what to look for in guns and pumps before you buy.
We can help you shape the record around your guns and your site. Send your equipment list and valve details through the contact form or by WhatsApp, and an engineer replies within 24 hours. You can also request the product guide through an enquiry.
Where a valve problem sits beyond injection, we will say so. We will then advise a proper assessment, because honest records lead to honest decisions.
Common questions
Sealant gun inspection record questions, answered directly
How often should I inspect a sealant gun?
Inspect before and after every job, and log each check. Guns in daily service need closer attention than guns used occasionally. Follow the maker guidance for your model, and set formal review intervals in your site rules.
What should a sealant gun inspection record include?
Record the date, equipment identity, condition of hose and fittings, valve tag, product and quantity injected, pressure response, and any stop-work events. Add the operator name and the date the next inspection is due.
When should a sealant gun be taken out of service?
Tag the gun out when the hose, couplings or fittings show damage, when seals weep, or when pressure climbs without product movement. Record the fault, and return the gun only after repair and a passed function check.
Do standards require injection equipment inspection records?
Standards generally defer operating and maintenance intervals to the equipment maker and the operator. Your site rules and permit system usually set the record keeping. Keep the log anyway, because it supports audits and incident reviews.
