Product details

Boss PLB103C is a clear RTV silicone sealant in a 3 oz. tube, the size that lives in a service tech's bag. It is meant for sealing up pool pumps, PVC fittings and the other small joints on an equipment pad that need a cured, flexible seal.

Where it earns its keep

RTV silicone cures at room temperature into a rubbery seal that stays flexible, which suits threaded fittings, housings and hairline gaps that a rigid adhesive would crack out of. Because it dries clear, a repair on white PVC or a pump body does not shout.

Sealant is not lubricant

O-rings that seal under compression, on pump lids, unions and filter tanks, want a lubricant such as Magic Lube, not sealant. Keep this tube for joints that need to set.

Questions and answers

What people ask about this product, answered by our pool techs.

What is it for?
Sealing pool pumps, PVC fittings and similar joints around the equipment pad. It is an RTV silicone, so it cures into a flexible rubber seal.
Is it clear when cured?
Yes, it is a clear silicone.
How much is in the tube?
3 oz.
Should I use this or an o-ring lubricant?
They do different jobs. An o-ring lube such as Magic Lube keeps an o-ring supple so it seals under compression; silicone sealant is for joints and surfaces that need a set, cured seal. Do not put sealant on an o-ring that is meant to be lubricated.
